Arlen Specter in the Tuesday primary."]Philadelphia, Pennsylvania (CNN) – Pennsylvania Rep. Joe Sestak expressed confidence Sunday that he would win the Senate Democratic nomination, but vowed to do all he can to defeat the likely Republican nominee if he fails to beat Sen. Arlen Specter in the Tuesday primary.
Sestak would not say he would endorse Specter, but rather noted he would "do anything to make sure we beat Pat Toomey," in the November general election. Toomey is the former GOP congressman, whose nomination for his party's candidacy is all but a formality.
"As I said, I come from a background in the military where the prospect of winning is the only, only option you have," Sestak told CNN in an interview
after addressing the congregation at the Mount Ephraim Baptist Church. "But I'll do anything to make sure that Pat Toomey doesn't win. But we're gonna win. Pat Toomey is gonna lose."
