One of the major
battlegrounds for this issue concerns
terminology. In keeping with our
Standards of Credibility, the
language used here is descriptive and
precise. Hence, expressions such as
“pro-life” and “pro-choice” are replaced by
words that describe specific positions.
In accord with the
journalism standard to “never use … a
scientific word or a jargon word if you can
think of an everyday English equivalent,”
[1]
[2]
the term used by Just Facts to describe the
object of an abortion is “preborn human.”
This conveys reality in everyday language
and is consistent with medical textbooks,
which use the word “human” when
referring to life before birth.[3]
[4]
[5]
[6]
* Following are facts about
human development:
Fertilization
Fertilization normally
takes place within one day of intercourse.[7]
At fertilization, the genetic composition of
a preborn human is formed.[8]
This genetic information determines gender,
eye color, hair color, facial features, and
influences characteristics such as
intelligence and personality.[9]
4 Weeks after
Fertilization
The heart is beating and a
circulatory system is in place.[10]
The portion of the brain associated with
consciousness and internal organs such as
the lungs are beginning to develop and can
be identified.[11]
7 Weeks after
Fertilization
Muscles and nerves begin
working together. When the upper lip is
tickled, the arms move backwards.[12]
The portion of the brain associated with
consciousness has divided into halves.[13]

9 Weeks after
Fertilization
More than 90% of the body
structures found in a full-grown human are
present. The medical classification changes
from an embryo to a fetus. From this point
forward, most development involves growth in
existing body structures instead of the
formation of new ones.[15]
[16]
10 Weeks after
Fertilization
All parts of the brain and
spinal cord are formed. The heart pumps
blood to every part of the body.[17]
The whole body is sensitive to touch except
for portions of the head. The preborn human
makes facial expressions.[18]
11 Weeks after
Fertilization

16 Weeks after
Fertilization
The preborn human makes eye
movements.[20]

18 Weeks after
Fertilization
The portion of the brain
responsible for functions such as reasoning
and memory has the same number of nerve
cells as a full-grown adult.[22]

20 Weeks after
Fertilization
The preborn human sleeps,
awakes and can hear sounds.[25]

Up through approximately
this point in time, according to the Supreme
Court’s rulings in Roe v. Wade and Planned
Parenthood v. Casey, a pregnant woman can
abort at will. (More details in the section
on
Constitution and
Law.)
24 Weeks after
Fertilization
The grip is strong enough
to hold onto an object that is moving up and
down.[27]
If born and given specialized care, the
survival rate is more than 80%.[28]
32 Weeks after
Fertilization

(Premature infant – 3 days after birth)
38 Weeks after
Fertilization
Average point in time when
humans are born.[29]
At any point prior to
birth, according to the Supreme Court’s
rulings in Roe v. Wade, Doe v. Bolton, and
Planned Parenthood v. Casey, a pregnant
woman can abort to preserve her “health.”
One example from Roe v. Wade of what may be
considered harmful to a mother’s health is
the work of caring for a child. (More
details in the section on
Constitution and
Law.)
* The 2008 Democratic Party
Platform states that abortion should be
generally legal, supports the Supreme Court
ruling in Roe v. Wade, and supports the use
of taxpayer funding to perform abortions.[30]
* The Republican Party
Platform states that abortion should be
generally illegal and supports a
Constitutional Amendment that would assure
preborn humans the right to life. It opposes
“using public revenues to promote or perform
abortion.”
[31]
* In interviews conducted
in August 2008, John McCain and Barack Obama
were asked, “At what point does a baby get
human rights?”
Barack Obama responded in
part:
|
I think that
whether you are looking at it
from a theological perspective
or a scientific perspective,
answering that question with
specificity, you know, is above
my pay grade.[32] |
John McCain responded in
part:
|
At the moment
of conception.[33] |
* John McCain’s 2008
presidential campaign web site states that
“Roe v. Wade is a flawed decision that must
be overturned…”
[34]
* Barack Obama and Hillary
Clinton have voiced support for Roe v. Wade
and stated that this would be reflected in
their appointments to the Supreme Court.[35]
[36]
[37]
They have also stated that they support a
ban on late term abortions, but only with an
exception for the “health” of the mother.[38]
[39]
* The Roe v. Wade verdict
provides several examples of what may
constitute a risk the health of the mother.
These include the “stigma of unwed
motherhood” and the “distress” “associated
with the unwanted child.” Roe v. Wade and
Doe v. Bolton, which were issued by the
Supreme Court on the same day with the order
that they “are to be read together,” mandate
that abortion be legal up until the point of
birth if any one physician willing to
perform an abortion decides it is necessary
to preserve a mother’s health.[40]
[41]
(More details in the section on
Constitution and
Law.)
* The President of the
United States appoints judges to the Supreme
Court. These appointments must be approved
by a majority of the Senate.[42]
Once seated, federal judges serve for life
unless they voluntarily resign or are
removed through impeachment.[43]
* For implications relating
to the appointment and approval of judges,
see the section on
Constitution and
Law.
* The website of Planned
Parenthood states:
|
In the two
decades before abortion was
legal in the United States,
nearly one million women went
“underground” each year for
illegal operations. Thousands
died for lack of medical care.[44] |
* No sources are cited for
the statements above. According to the U.S.
Centers for Disease Control, whose death
statistics from legal abortions have been
accepted and used by Planned Parenthood,[45]
[46]
[47]
in the year before Roe v. Wade (1972), there
were 39 deaths from illegal abortions. In
the year after Roe v. Wade (1974), there
were 26 deaths from legal abortions.[48]
*
Citing data from the Centers for Disease
Control, a Planned Parenthood Fact Sheet
asserted that the “risk of death associated
with childbirth is about 10 times as high as
that associated with abortion.”
[49]
[50]
[51]
*
From 1989 through 1992, the Centers for
Disease Control reported zero
abortion-related deaths in the state of
Maryland.[52]
[53]
[54]
[55]
*
During 1989 in the state of Maryland:
- Erica Kae Richardson (16 years-old)
was admitted to an emergency room on March 1st
with a punctured uterus from an abortion
carried out earlier that day at a clinic in
Laurel, Maryland. She died shortly after
midnight on March 2nd.[56]
[57]
[58]
[59]
- Paramedics arrived at an abortion
clinic in Suitland, Maryland on July 12th
to find Debra M. Gray (34 years-old) in
cardiac arrest after being administered
anesthesia without the presence of an
anesthesiologist. She was taken to a
hospital and died three days later.[60]
- Paramedics arrived at an abortion
clinic in Suitland, Maryland on September 10th
to find Susanne Renee Logan (32 years-old)
in cardiac arrest with an oxygen mask placed
upside down on her face. It was found that
she had been given anesthesia without the
presence of an anesthesiologist. The
paramedics resuscitated Ms. Logan, she
stayed in a coma for four months, and was
generally paralyzed until her death in 1992.[61]
[62]
[63]
- Gladys Estanislao, a 28-year-old college
student, was found lifeless on a bathroom
floor 17 days after undergoing an abortion
procedure at a clinic in Bethesda, Maryland.
Her autopsy revealed that the pregnancy was
not in her womb, but in her fallopian tube,
which caused it to rupture and resulted in
her death.[64]
[65]
[66] This condition, called an ectopic
pregnancy, is screened by a blood test or
ultrasound, has a mortality rate of 1 in
2,000, and is typically diagnosed on the
first visit to a gynecologist.[67]
[68]
[69]
* In
1987, the New York City Commissioner of
Health wrote a letter to abortion clinics
warning them to be careful about using too
much anesthesia. The letter stated:
|
During the
period between 1981 and 1984,
there were 30 legal
abortion-related deaths in New
York City.[70] |
* For the same time period,
the Centers for Disease Control reported a
total of 42 legal abortion-related deaths in
the United States.[71]
* If both of these numbers
are accurate, it would mean that 71% of the
legal abortion-related deaths in the United
States occurred in one city where about 3%
of the population lived.[72]
* An “Abortion Services”
page on Planned Parenthood’s website states:
|
Abortion
DOES NOT …
• Cause
premature birth, birth defects
or low infant birth weight in
future pregnancies
• Increase the
chance of infant death in the
future
[73] |
* A 2007 paper in The
Journal of Reproductive Medicine cites
59 studies that exhibit an association
between abortion and the risk of premature
births in later pregnancies. In five of the
largest and more recent of these studies,
all found increases in premature births in
women who had an abortion. All of these
studies also found that this risk escalated
when more than one abortion was performed.[74]
Children born prematurely are at increased
risks for early death, cerebral palsy,
blindness, deafness and other health
complications.[75]
* In April of 2007 at a
political event in Iowa, John McCain stated:
|
… I have a
steadfast and strong advocacy
and voting record in support of
the rights of the unborn.[76] |
* At the same event, Mike
Huckabee stated:
|
I’m not late
in declaring that I believe life
begins at conception and that we
ought to protect human life…
[77] |
* In an article about this
event in the New York Times written by Adam
Nagourney, it is stated that John McCain and
Mike Huckabee “presented themselves as
lifelong opponents of abortion rights.” Four
times in this article, candidates are
characterized as opponents of abortion
rights and never as supporters of rights for
the unborn.[78]

* Roe v. Wade and its
accompanying ruling, Doe v. Bolton, mandate
that abortion be legal up until the point of
birth if any one physician willing to
perform an abortion decides it is necessary
to preserve a mother’s “health.”
[80]
[81]
* In January 2002, the
Gallup polling organization reported:
|
If Roe v.
Wade is presented only as
legalizing abortion in the first
three months, support for the
decision is much higher than if
it is characterized as making
abortion legal throughout
pregnancy or for any reason.[82] |
* Since this time, the
Associated Press, Quinnipiac University, the
Pew Research Center, NBC News, the Wall
Street Journal, and Harris Poll have all
conducted polls in which they characterized
Roe v. Wade as making abortion legal in the
first “three months of pregnancy.”
[83]
* In three articles
published by the Associated Press in 2007
and 2008, it is asserted that the United
States “permits abortions within the first
12 weeks of pregnancy.”
[84]
Media outlets that carried one or more of
these stories include ABC, CBS, MSNBC, Fox
News, Yahoo News, AOL News, USA Today, Los
Angeles Times, Boston Globe, Washington Post
and more than 50 other local, state,
national and international publications.[85]
* As of June 2008:
- 35 states have a law in effect that
requires parental consent or notification
for a minor to have an abortion.[86]
[87]
- 7 states have a parental consent or
notification law that is being blocked by a
court.[88]
[89]
- 8 states have no laws requiring
parental consent or notification for
abortions.[90]
* In the State of New
Hampshire, it is against the law for anyone
under 18 years of age to get a body piercing
unless their parent or guardian is
physically present when it is performed and
signs a consent form.[91]
* In the State of New
Jersey, it is against the law for anyone
under 18 years of age to get a tattoo or
body piercing without written consent from
their parent or legal guardian.[92]
* In the State of
California, it is against the law for anyone
under 18 years of age to use a tanning
machine without written consent from their
parent or legal guardian.[93]
* In New Hampshire, New
Jersey and California, it is legal for a
girl of any age to get an abortion without
her parent’s consent or knowledge.[94]
[95]
[96]
* The Democratic Party
Platform makes no explicit reference to
parental consent or notification laws.[97]
The Republican Party Platform supports
parental notification laws and makes no
explicit reference to parental consent laws.[98]
*
John
McCain is a cosponsor of a bill to prohibit
transporting minors across state lines to
evade state laws that require parental
involvement in a minor’s abortion.[99]
*
Sarah Palin supports parental consent
legislation and when Alaska’s Supreme Court
struck down such a law in a 3-2 decision,
she backed a constitutional amendment
aimed at restoring it.[100]
[101]
[102]
* On a 2001 vote in the
Illinois Senate for a parental notification
bill, Barack Obama voted “Present.”
[103]
[104]
*
Illinois
Senate rules state that “a majority of
those elected” must vote in favor of a bill
for it to pass. Thus, a vote of “Present”
has the same result as a vote of “No.”
[105]
* A 2000 U.S. Department of
Justice study found that the incidence of
forcible rape peaked at the ages of 14 and
15.

* Arkansas law requires
written consent of a parent (not a
step-parent) before an abortion is performed
upon a female who is less than 18 years of
age.[107]
In 2006, a 15-year-old Arkansas girl accused
her 41-year-old stepfather of raping her,
getting her pregnant, forcing her to have an
abortion in Illinois (where there is no
parental consent or notification law in
effect), and continuing to rape her
afterwards.[108]
[109]
[110]
[111]
* The girl’s claim that she
was taken to an abortion clinic in Granite
City, Illinois was corroborated by a photo
of her stepfather’s car at this facility.[112]
He was arrested, charged with a dozen counts
of rape and committed suicide before trial.[113]
[114]
* In 2006, the U.S. House
of Representatives passed a bill that would
have required abortion providers in states
without parental involvement laws to give at
least 24 hours notice to a parent before
performing an abortion on a minor who
resides in another state. This provision
included exceptions for parental abuse,
neglect, and if the physical health of the
minor was endangered.[115]
93% of Republicans voted for it and 71% of
Democrats voted against it. (Click for a record
of how each Representative voted.)
* After being approved by
the House, the bill was sent to the Senate
where it was blocked by 37 Democrats, 4
Republicans, and 1 Independent. This
included Hillary Clinton, Joe Biden, Barack
Obama, Arlen Specter and Olympia Snowe. (Click for a record
of how each Senator voted.)
* Partial birth abortion,
as explained in the New York Times, entails
when a preborn human
|
is partly
extracted from the birth canal,
feet first, and the brain is
then suctioned out.[116]
[117] |
* According to the
executive director of the National Coalition
of Abortion Providers, this procedure was
typically performed at 20+ weeks.[118]
* Preborn human at 20 weeks
after fertilization:

* During Bill Clinton’s
presidency, two bills to ban partial birth
abortion were passed by Congress. In both
cases, at least 90% of Republicans voted for
the bill and more than 60% of Democrats
voted against it. Clinton vetoed both of
these bills and neither became law.[120]
[121]
[122]
[123]
[124]
[125]
* During George W. Bush’s
presidency, Congress passed a bill to ban
partial birth abortions with 95% of
Republicans voting for it and 62% of
Democrats voting against it.
(Click for a record of
how each Congressman voted.) Bush signed
this bill into law in November 2003.[126]
[127]
[128]
* This law does not ban
late-term abortions; only the partial birth
procedure.[129]
It does not prohibit giving a lethal
injection to a preborn human and performing
a partial birth abortion afterwards.[130]
It does not prohibit dismemberment
abortions, in which “the fetal limbs are
pulled off the body in utero, sometimes
while the fetus is still alive.”
[131]
[132]
* After this law was
enacted, several abortion providers
challenged it in court.[133]
In 2007, the U.S. Supreme Court upheld the
law in a 5-4 vote.[134]
Of the five Supreme Court justices who ruled
to uphold the law, Barack Obama voted
against the nomination of two of them and
identified two of the others as judges he
would not have nominated.[135]
[136]
[137] Of the four justices who
voted to strike down the law, John McCain
has identified all of them as judges he
would not have nominated.[138]
* The day after the Supreme
Court ruling was issued, Democrats in the
U.S. Senate and House of Representatives
introduced legislation that would overturn
the ban on partial birth abortions.[139]
[140]
[141]
[142] Barack Obama has stated
that the “first thing” he would do as
President is sign this bill into law.[143]
* In March of 1970, a
pregnant woman by the name of Norma McCorvey
sued the state of Texas to challenge a state
law that prohibited abortion except to save
the life of the mother. McCorvey wanted to
keep her identity secret and assumed the
fictitious name Jane Roe. The name of
the district
attorney responsible for enforcing
the law was Henry Wade. Thus, the case was
entitled Roe v. Wade.[144]
[145]
[146]
* In 1973, the Supreme
Court released its ruling. Seven of the
judges ruled in favor of Roe and two of the
judges opposed the ruling. The ruling
overturned the laws of 30 states that
prohibited abortion except to save the life
of the mother.[147]
* The majority created
rules regarding the types of abortion
legislation that states could enact based
upon the three trimesters of a typical
pregnancy:
- First trimester: States cannot
prohibit abortions. They can require that
abortions be done by licensed physicians,
but other than this, they cannot regulate
the manner in which they are performed.[148]
- Second trimester: States cannot
prohibit abortions. They can regulate the
manner in which they are performed for the
purpose of protecting the mother’s health.[149]
- Third trimester: States can prohibit
abortions after “viability” (meaning the
point where a preborn human is capable of
living outside their mother’s womb), but
cannot prohibit abortions “where it is
necessary, in appropriate medical judgment,
for the preservation of the life or health
of the mother.”
[150] The ruling cites examples
of what may be considered harmful to a
woman’s health. These include the “stigma of
unwed motherhood,” the work of caring for a
child, and the “distress” “associated with
the unwanted child.”
[151]
[152]
* On the same day that the
Supreme Court released Roe v. Wade, it
issued another ruling in a case entitled Doe
v. Bolton. The same seven judges who ruled
in favor of Roe also ruled in favor of Doe,
and the same two judges opposed the ruling.[153]
The majority wrote that this ruling and Roe
v. Wade “are to be read together.”
[154]
* In this case, the State
of Georgia had a law prohibiting abortions
unless the pregnancy would “seriously and
permanently” injure the health of the
mother.[155]
A lower court struck down this law and the
majority of the Supreme Court agreed. The
ruling stated that abortion laws with
exceptions for the health of the mother must
allow for factors such as emotional health,
psychological health, familial concerns, and
the woman’s age.[156]
* The Georgia law also
required that the doctor who would perform
the abortion, two other doctors, and a
committee of the medical staff at the
hospital where the abortion was to be done
needed to agree that the abortion was
necessary to preserve the health of the
mother.[157]
The Supreme Court struck this requirement
down, ruling that only the doctor who would
perform the abortion needs to determine that
the abortion was necessary to preserve the
health of the mother. Any abortion provider
could make this decision based solely on
their “best clinical judgment.”
[158]
* In 1992, the Supreme
Court decided a case entitled Planned
Parenthood v. Casey. In this case, the
majority reaffirmed the central element of
Roe v. Wade, but did away with the “rigid
trimester framework.”
[159]
* As in Roe v. Wade, the
majority ruled that states cannot prohibit
abortions prior to viability, and laws that
prohibit abortion after viability must
include an exception for the “health of the
mother.”
[160] (With regard to viability,
as of 2007, the youngest premature baby to
survive was born at 21 weeks and 6 days
gestation.[161])
* Contrary to Roe v. Wade,
the majority ruled that states could enact
laws that regulated abortion throughout
pregnancy, as long as they did not create a
substantial obstacle to obtaining an
abortion. An example of what would be
acceptable is a law requiring that doctors
provide women with certain information
before they perform abortions.[162]
* A 2007 British study
found that 3.2% of preborn humans aborted on
the basis of diagnoses for conditions such
as Down’s Syndrome, heart defects, and
kidney problems, survived for a median time
of 80 minutes after birth, 36% of them for
an hour or less, 6% for six hours or more.[163]
* The Encyclopedia of
Human Biology states:
|
Attempts to
suckle have been seen … in
aborted fetuses of 3 months.[164] |
* In 2003, a child was born
in Britain at 24 weeks gestation following
three abortion procedures. As of 2005, he is
healthy and is the “first long-term abortion
survivor” to be born this prematurely.[165]
[166]
* Gianna Jessen was born in
1977 after surviving an abortion at
seven-and-a-half months gestation.[167]
[168] She has cerebral palsy as a
result of the procedure.[169]
She is now 31-years old and is a marathon
runner, writer, singer, and “travels the
world to campaign against abortion.”
[170]

* In July 2000, two
registered nurses who worked in the labor
and delivery unit of Christ Hospital in Oak
Lawn, Illinois testified before a U.S.
Congressional subcommittee. Both described
instances at the hospital in which they had
personally seen babies who were born alive
after an abortion and left to die without
any care or comfort provided.[171]
[172] A spokesman for the
hospital’s parent corporation estimated that
10-20% of the abortions it performs on
preborn human with genetic defects result in
live births for short periods of time.[173]
* In 2001 and 2002,
identical bills were introduced in the
Illinois legislature with three paragraphs
of operative text stating that anyone “born
alive at any stage of development” is
considered a “person” under Illinois state
law including those born as a result of
“abortion.”
[174]
[175] Barack Obama, as an
Illinois state senator, voted against both
of these bills.[176]
[177]
* In 2002, the U.S. House
of Representatives passed by a voice vote,
the U.S. Senate passed by unanimous consent,
and President Bush signed a bill stating
that anyone “born alive at any stage of
development” is considered a “person” under
federal law including those born as a result
of “abortion.”

“This genetic material will
determine your baby’s sex, eye
color, hair color, body size, facial
features and – at least to some
extent – intelligence and
personality. … Your baby’s sex is
determined at the moment he or she
is conceived.”

[P]rimary cerebral vesicles appear. … Rudimentary limb buds appear and the heart tubes fuse into a common loop in which contractile activity commences. The primordia of the thyroid gland, lungs, liver, pancreas, and mesonephric tubules are all identifiable.

52-53:
In the sixth and seventh weeks, nerves
and muscles work together for the
first time. If the area of the lips,
the first to become sensitive to
touch, is gently stroked, the baby,
who then is still an embryo,
responds by bending the upper body
to one side and making a quick
backward motion with the arms. This
is called a “total pattern” response
because it involves most of the body
rather than the approximate local
part.”
