Kristol found Palin for McCain. He took a trip up to Alaska and was a big supporter of her.
Seems he is miffed she stepped down from her office as Governor.
I dont like either Palin (most recently because of her shameless role of goading Obama into the Libya mess) or Kristol but I suspect that Kristol abandoned her because he follows the standard neocon credo: the rats should always leave a sinking ship. If Sarah were higher in the polls, he’d still be her biggest booster.
