Sen. Arlen Specter, looking ahead to a potential GOP primary more than a year away, launches a negative ad against Pat Toomey.

Toomey’s not even in the race yet (although he’s expected to jump in within a week).

It’s habit, apparently, as he hit Toomey for voting against pork in the 2004 primary.

You know, if he keeps this up, he’s going to give politicians a bad name.

UPDATE: Pssst. Toomey! The website URL that Specter’s campaign used last time, www.toomeystroubles.com, appears to be available.
