Bill Kristol’s been clinging to that last thread of credibility for a while now, but that thread appears to have finally snapped.

Last night, he went after Rudy Giuliani for not being “tough” enough to take on Hillary Clinton in the 2000 race for U.S. Senator from New York:

Or as people do when confronted by … cancer.

Just a tad.

You don’t have to be a Rudy Giuliani fan to be able to appreciate that choosing to battle cancer instead of running for office has nothing to do with being a coward. Bill Kristol’s clearly not a Rudy Giuliani fan, but he’s apparently a huge fan of getting called out as a jackass.

He has no shame, but on the very, very off chance he deletes it:

Everybody’s clapping for you, Bill. Take a bow.

Oh, he’ll do it again. It’s only a matter of time.

It used to be. Not anymore.
