Sestak's in

"One step closer to the Whitehouse!", cackles Tim the Enchanter.

Rep. Joe Sestak announced on Tuesday he would challenge Republican-turned-Democrat Sen. Arlen Specter, setting the stage for a Pennsylvania primary race likely to center on Specter’s Democratic credentials.

Sestak, a former Navy vice admiral, made the announcement at a crowded VFW hall in Folsom in his suburban Philadelphia district, near where he grew up. He scheduled five campaign stops in Pennsylvania on Tuesday and Wednesday.

He is actually a retired RADM ... but you have to click the Sestak tag to get the details.
