The 2012 GOP Platform makes Republican support for an outright ban on abortion, no exceptions for rape, incest, or the life of the mother, once again official, emphasis mine:
“Faithful to the ‘self-evident’ truths enshrined in the Declaration of Independence, we assert the sanctity of human life and affirm that the unborn child has a fundamental individual right to life which cannot be infringed. We support a human life amendment to the Constitution and endorse legislation to make clear that the Fourteenth Amendment’s protections apply to unborn children.”
According to Think Progress, the amendment “would outlaw abortion and likely many forms of contraception”, emphasis mine:
Heading the committee is Gov. Bob McDonnell (R-VA), best known for his “mandatory ultrasound” law requiring any woman getting an abortion to undergo an unnecessary ultrasound. McDonnell also revealed his regressive position on women’s rights in his college thesis, which slandered working women, contraception, and “fornicators.” It’s no surprise, then, that under his guidance, the Republican Party will reaffirm its support for a constitutional amendment that would outlaw abortion and likely many forms of contraception.
In saying they would not oppose a rape exception, Romney and Ryan are both changing their tune. Romney said in 2007 he would be “delighted” to sign a bill banning all abortions, and Ryan has been staunchly anti-abortion in all cases, even attempting to restrict abortion access to victims of “forcible rape” only.
The human life amendment has been a tenet of the Republican Party platform since the dawn of the Reagan era in 1980.
Also, you should read this in order to grasp just how far Republicans are willing to go to strip women not only of choice, but of dignity.
