Razib Khan asks if there is a anti-evolution litmus test for GOP presidential candidates:
I’m on the record as saying that predictions for 2012 are very premature. But, it looks like 3 of the front-runners for the G.O.P. nomination are rather frank Creationists (Palin, Huckabee and Pawlenty). I’m skeptical about any of these as likely candidates (i.e., if you had to make a bet you’re going to be surprised), but if you keep adding individuals to the list it seems likely that we’re looking at a serious probability that the G.O.P. nominee in 2012 will be a Creationist. Creationism doesn’t really have the same valence as abortion as a “culture war” issue, but, it useful in being a distinctive marker for social conservative candidates. Mitt Romney is now notionally as pro-life as the social conservatives, but it seems unlikely that he’ll flip his position on evolution since he expressed himself so explicitly in the 2008 debates.
