At last night's Republican in Arizona, Rick Santorum took considerable flack for his endorsement of the libertarian Arlen Specter over the more conservative Pat Toomey. But each candidate has some endorsement skeletons in their own closets. Be it endorsing the guy who wanted to impeach Bush, the candidate who dropped out and campaigned for the Democrats, the guy who helped pass ObamaCare, or the four third party candidates with fringe views, all the 2012 candidates have some endorsement they probably now regret.
