Rep. Joe Sestak (D-Pa.), who is challenging Sen. Arlen Specter (D-Pa.) in the Democratic Senate primary, cited Specter's support for the North American Free Trade Agreement in his pushback against the senator's three new TV ads.

"Pennsylvania workers have lived the effects of Arlen Specter's failed economic policies for 30 years," the Sestak campaign said in a statement. "NAFTA has cost 45,000 Pennsylvanians their jobs. It displaced hundreds of thousands of workers into lower-wage positions, exploded our trade deficit, and dealt a major blow to American manufacturing."

Specter released three TV spots Wednesday that are airing in "various locales across the state," according to his campaign. The ads feature blue-collar workers who say that the Democrat helped them land jobs or protected their pensions. Consultant Chris Mottola produced the spots.

They're the first TV ads of the Pennsylvania Senate Democratic primary.
