You can say a lot of things about Christopher Hitchens. That he minces words is not one of those things:

The most insulting thing that a politician can do is to compel you to ask yourself: "What does he take me for?" Precisely this question is provoked by the selection of Gov. Sarah Palin. I wrote not long ago that it was not right to condescend to her just because of her provincial roots or her piety, let alone her slight flirtatiousness, but really her conduct since then has been a national disgrace. It turns out that none of her early claims to political courage was founded in fact, and it further turns out that some of the untested rumors about her—her vindictiveness in local quarrels, her bizarre religious and political affiliations—were very well-founded, indeed. Moreover, given the nasty and lowly task of stirring up the whack-job fringe of the party's right wing and of recycling patent falsehoods about Obama's position on Afghanistan, she has drawn upon the only talent that she apparently possesses.

The rest of Hitchens' article at Slate is similar. For a guy who has spent the last few years concentrating all his ferocity towards those who didn't want to be in Iraq, an unwillingness to back McCain must truly mean the wheels are off.
