Public Policy Polling released new surveys from Pennsylvania on the competitive governor and Senate races. In the governor's race (June 19-21, 609 RV, MoE +/- 4.0%), Republican Tom Corbett holds a 10-point lead over Democrat Dan Onorato, thanks in large part to Democrats' reluctance to get behind Onorato.

Just 57% of his party's voters currently back Onorato, while Corbett pulls 21% of Democrats. Onorato may be growing his support among his own party after a competitive primary process, but Corbett's favorability rating has grown among Republicans, Democrats and independents.

"If Dan Onorato can haul his own party members back into the fold over the next four months, he could still win," said PPP president Dean Debnam. "If not, it looks like the governorship will continue its 40-year back-and-forth trend between the two parties."

In the Senate race, Democrat Joe Sestak is running even with Republican Pat Toomey. In the three polls released since Sestak defeated Sen. Arlen Specter in the May 18 primary, including this one, Sestak has led, trailed and now tied Toomey.

After a divisive primary, Sestak now has the support of 70% of Democrats, while Toomey does about the same with Republcans -- 73%.

"Joe Sestak is tied with Pat Toomey even though we see a Pennsylvania electorate for this fall that is much more Republican friendly than the one that turned out two years ago," said Debnam. "If Democrats can get their voters more engaged they'll be favored here."
