What's going on? Given that he's already claimed that humans cause global warming (and been endorsed by Al Gore for it), refused to back away from Romneycare, and come out in favor of ethanol subsidies, it seems that he would want to have something left in the political war chest. It won't be pro-life credentials, though, seeing as how he refused to sign the Susan B Anthony List pledge to only appoint pro-life judges and cabinet members:
Romney is one of three Republican candidates who has declined to sign the pledge, which is sponsored by the Susan B. Anthony List, a Washington-based pro-life advocacy group. Candidates who signed the pledge have promised to nominate to the Supreme Court and federal courts only judges "who are committed to restraint and applying the original meaning of the Constitution, not legislating from the bench."
Former Godfather's Pizza CEO Herman Cain and former New Mexico Gov. Gary Johnson are the other two candidates who have refused to sign the pledge. Former Minnesota Gov. Tim Pawlenty, Rep. Michele Bachmann (R-Minn.), Former Speaker of the House Newt Gingrich (R-Ga.), Rep. Ron Paul (R-Texas) and former Sen. Rick Santorum (R-Pa.) have all signed it.
The SBA List said in a press release that they are "calling on pro-life activists to put pressure on those candidates who have refused to sign."
