Ad blitz levels playing field in Pa. Senate race

Rep. Joe Sestak (D-Pa.) has pulled even with Sen. Arlen Specter (D-Pa.) in the Muhlenberg College/Morning Call daily tracking poll released Friday. The rivals for the Pennsylvania Senate nomination are tied at 43 percent with 13 percent undecided. 

Sestak has been trailing consistently behind Specter, who has wider name recognition. But his TV ad blitz in recent days may have had an impact.
