Joe Sestak Wins Democratic Senate Nomination in Pennsylvania

Senator Arlen Specter of Pennsylvania, who bolted the Republican Party 11 months ago in a bid to salvage his Senate career as a Democrat, was defeated in a primary for his new
party's nomination on Tuesday, as Democratic primary voters turned against him and selected Representative Joe Sestak for the nomination.

Mr. Specter, 80, lost his bid for a sixth term despite the backing of a wide swath of the Democratic political establishment -- starting with President Obama in the White House and continuing with Ed Rendell, the governor of Pennsylvania.

Let's review -- bolted the Republicans and is 80 years old. If you can't stick with your convictions when you're 80, it's time to give up your Senator card.
