A new poll released Tuesday shows the race for Pennsylvania governor shaping up to be a blowout as Democrat Tom Wolf leads Republican incumbent Tom Corbett by 25 points.

A new Public Policy Polling poll shows Wolf with a 55-to-30 lead over Gov. Tom Corbett, double the 12-point lead the Democrat held over Corbett in November of last year when PPP released its last statewide poll.

"Things aren't getting any better for Tom Corbett," said Dean Debnam, president of Public Policy Polling. "His approval numbers are as poor as they've ever been, and Tom Wolf is starting out as an unusually well-liked candidate for governor even on top of that."

The poll finds that only 27 percent of Pennsylvania voters approve of the job Corbett is doing in office, compared with 58 percent who disapprove. Wolf, on the other hand, has a 47 percent favorability rating among voters.

Corbett can find some good news in the polling, however. His decision not to appeal the court decision legalizing gay marriage in Pennsylvania was viewed by 56 percent of residents as the right decision. However, those numbers may indicate a shift to the left on social issues, which could be a problem for Corbett in November.

PPP surveyed 835 registered voters from May 30 to June 1.
