Sen. Arlen Specter's (D-PA) last general election challenger -- former Rep. Joe Hoeffel (D-PA) -- told the Delaware County Daily Times that he would back Rep. Joe Sestak (D-PA) in a primary against Specter.
Said Hoeffel: "If Joe Sestak runs in the primary, I will support him. I admire him very much and think he will be a strong candidate for whatever he runs for, including reelection."
