Pennsylvania Rep. Joe Sestak's Democratic primary challenge to Sen. Arlen Specter has yet to pick up steam, as a new Quinnipiac survey finds him trailing by 21 points in the May 18 contest.

"With less than six weeks until the May 18 primary, Sen. Arlen Specter looks to be in solid shape for the Democratic nomination," said Quinnipiac assistant director Peter Brown. "Not only would Sestak have to win every undecided vote, he also would have to take away some who say they are for Specter."

Specter's favorable rating is twice as high as Sestak's, as nearly 6-in-10 Dem primary voters still say they don't know enough about the congressman.

The Democratic primary for governor, however, is much closer as Allegheny Co. Executive Dan Onorato, Joe Hoeffel and state Auditor General Jack Wagner finish within 7 points of each other. Meanwhile, Attorney General Tom Corbett holds a 58%-7% lead over state Rep. Sam Rohrer in the GOP primary.

"Dan Onorato remains slightly ahead as he has since the campaign began, but his margin is so small and the undecided vote so large that at this point the race is a three-way toss-up," said Brown.

The survey was conducted March 31-April 5 of 921 Dem LV with a MoE of +/- 3.2%.
