Democrat to Challenge Specter

Arlen Specter switched to the Democratic Party so he could cruise to reelection in 2010, but he may have to fight for his life anyway: Talking Points Memo is reporting that Rep. Joe Sestak “is privately telling supporters that he intends to run for Senate.” According to his sister, “He intends to get in the race.” TPM also has its hands on a memo handwritten by Sestake that says, “"I am writing you as especially dear supporters to let you know I intend to run for the U.S. Senate.”
