A national organization that helps Democrats get re-elected to the U.S. Senate is spending money to help Pennsylvania Sen. Arlen Specter fend off a primary challenge.
A Democrat Senatorial Campaign Committee spokesman said Wednesday the organization is helping pay for a TV ad airing in the Philadelphia area that shows Specter speaking about his record in front of a backdrop of the city's skyline.
Spokesman Eric Schultz wouldn't say how much the committee spent or whether it plans further aid. Specter campaign manager Chris Nicholas wouldn't comment.
The ad comes as a new Quinnipiac (KWIHN'-uh-pee-ak) University poll shows challenger Joe Sestak closing in on Specter, who switched parties last year.
Specter is leading, 47 percent to 39 percent, but that's narrowed from a 21-point gap a month ago.
