Pennsylvania Gov. Ed Rendell (D) predicted that his preferred candidate will win the state's Senate primary on Tuesday.

Rendell backs Republican-turned-Democratic Sen. Arlen Specter, who is facing a challenge from Rep. Joe Sestak (D-Pa.)

“It’s going to be close. I think in the end Specter will pull it out. People will realize the value of his service to the state over the last 30 years," he said on Fox Business Network. “That [the African-American vote] is certainly a cornerstone for him. But the rain here is a factor. We’ll see how that affects the turnout.”

On Monday, Rendell simply predicted that the race would be close, but on Tuesday, he expressed a bit more confidence in Specter. 

Polls generally show Specter locked in a statistical tie with Sestak, despite the support the incumbent senator has from Rendell and the White House.
