As I reported yesterday, Rep. Joe Sestak (D-PA) is putting the screws to his primary opponent, incumbent Sen. Arlen Specter (D-PA) by launching a website tying Specter to his 30 year record as a Republican.

The site, which bares a non-coincidental resemblance to Specters actual campaign site, has since gone live; you visit it here. Perhaps most damningly, it includes one image tying Specter to liberal bete noir Sarah Palin.

A letter from the Sestak campaign warns, "This election, Pennsylvania will have a choice between a principled, accountable leader for the next generation or two long-time Republicans." (Whoever wins the Democratic Senate primary will face conservative Pat Toomey in the general election.)
