I took a lot of grief from some conservatives for this post from Friday, the day the Gov. Palin pick was announced, discussing whether and how Sen. McCain could withdraw Palin as his VP candidate if necessary. The post was characterized by some as “liberal wishful thinking.” Perhaps. But with the many revelations about governor Palin, perhaps most importantly her ties to the Alaska secessionist party, the American Independence Party (whose leader has suggested that members “infiltrate” the two major parties), I think withdrawal of the expected nomination before the election is a real possibility. Real enough that Intrade has started taking bets on the question.
