John McCain’s newest tactic: Sarcasm.

The political judo at work is stunning.

McCain, and his newly-appointed Rovian-disciples, are making Obama’s celebrity, or more precisely the affection and genuine admiration the public feels towards him, a liability. It’s the underdog play. Everyone hates a winner, they must be thinking.

Transparent and amateur, but you can see it working, to a point. Sadly, in any underdog play, the underdog has to be lovable. McCain is hardly lovable.
