Yeah... His judgment is suspect.
http://en.wikipedia.org/wiki/William_Kristol
In the 2000 Presidential election, Kristol was a supporter of John McCain. In response to a question from a PBS reporter about the Republican primaries, he stated, "No. I had nothing against Governor Bush. I was inclined to prefer McCain. The reason I was inclined to prefer McCain was his leadership on foreign policy."
The only reason he ever defended Palin to begin with is because McCain chose her as his VP. It's dishonest to pass Kristol off as a Reagan conservative that now has seen the light and opposes her. Typical media hit piece.
