Nor do I. But if one wanted to make the case that "Palin is a RINO!", based on past photos or endorsements--as some are doing with Bachmann and others--that is how that game is played. I DON'T fault Palin for endorsing McCain in 2010, but then I also do not fault Bachmann for appearing at a rally together with Romney in 2008.
Many here DID that, and were hypocrites that ended up pushing DeMint and Paul.
