Dan Onorato is widening his lead in Pennsylvania's Democratic gubernatorial primary, while Arlen Specter's lead over his Senate Democratic primary foe seems to be shrinking.
Results of a Quinnipiac University poll were released Tuesday morning amid heavy TV advertising for the May 18 primary.
It shows U.S. Rep. Joe Sestak trailing Mr. Specter, 47 to 39 percent, among likely voters. The fifth-term incumbent led 53 to 32 percent a month ago.
In the four-way gubernatorial race, 36 percent support Mr. Onorato -- an increase from 20 percent for the Allegheny County executive.
State Auditor General Jack Wagner, state Sen. Anthony Hardy Williams and Montgomery County Commissioner Joe Hoeffel each scored below 10 percent.
