It's Rove.
Leftists are absolutely OBSESSED with destroying him.
There's been nothing like the Left's hatred for Karl Rove, since they (successfully) brought down Newt Gingrich. That success very strongly rewarded them for the "deliberate attack" tactic, and they've never ever forgotten its power. (didn't hurt that it very nearly worked against Justice Thomas, either)
Liberals now believe if they simply get angry and hysterical enough, they can bring down whomever they target... (Rove, at the moment)
