Specter Only Mocks Republicans At Pittsburgh Comedy Club

Most Republicans likely already think Sen. Arlen Specter (D-Penn.) is a joke, and Thursday evening he proved it when he took the stage at a Pittsburgh comedy club.

Appearing at the Improv in a benefit for Allegheny county's Music Festival Fund for children, Specter poked fun exclusively at Republicans including Bob Dole, Dan Quayle, Trent Lott, Alfonse D'Amato, and Howard Baker.

Proving just how much his allegiances have changed since his defection to the Democrats, although some of the material was taken from a previous routine he had done at the Washington Improv in 2007, a joke which back then involved Barack Obama, Hillary Clinton, and Joe Biden now featured Sarah Palin, John McCain, and Rudy Giuliani (videos in two parts embedded below the fold, sexual content warning, h/t Huffington Post):

In the end, Specter actually did a pretty good job, but couldn't he have done ONE joke about a Democrat?

Or is that not allowed now that he's one of them?
