Women’s reproductive rights haven’t been this threatened by a group of Republican presidential hopefuls in decades. As Rachel Maddow summarized brilliantly the other night, Rick Santorum, “libertarian” Ron Paul, Newt Gingrich, and Rick Perry have all signed pledges backing the Personhood movement that aims to make all abortions illegal (even in the case of rape and incest) by defining fertilized eggs as people, which would in turn ban most forms of birth control. Mitt Romney hasn’t signed anything yet, nor did he attend the Presidential Prolife Forum in South Caroline this past Wednesday like all the others, but he did tell Mike Huckabee last October that he “absolutely” would have supported a personhood amendment to his state’s constitution when he was Governor of Massachusetts. Rick Santorum is the only one — so far — who’s actually said out loud that birth control is “not okay” and is a dangerous problem in this country, but that kind of thinking is basically built into the personhood movement (whether these candidates, who will say anything to appease their religious base, realize it or not). So you know where these guys stand.
