Gov. Corbett is now in full re-election campaign mode but his popularity continues to tank. A Quinnipiac University Poll released this afternoon shows that 56 percent of registered voters in the state think Corbett doesn't deserve a second term next year.

The poll also found Corbett trailing the Democrats who want to challenge him in the 2014 general election. U.S. Rep. Allyson Schwartz leads Corbett 45-37 percent. A Democrat who has not even entered the race, former state Auditor General Jack Wagner, leads Corbett 48-36 percent.

State Treasurer Rob McCord puts up 42 percent against Corbett's 39 percent. Former state Secretary of Environmental Protection Katie McGinty leads Corbett 44-37 percent. Former state Revenue Secretary Tom Wolf leads Corbett 44-37 percent.

Corbett leads just one Democrat, former state Secretary of Environmental Protection John Hanger, 42-37 percent.

"Pennsylvania voters deliver a big bag of coal to Gov. Tom Corbett and directions to the State House exit as he heads into the holidays with the worst net approval rating he has ever had," Tim Malloy said in the poll release. Malloy is assistant director of the Quinnipiac University Polling Institute.

Corbett's campaign quickly shrugged off the bad numbers.

"This race will be a marathon not a sprint," Corbett campaign manager Mike Barley said. "Governor Corbett is well within striking distance of his opponents, who are still struggling with very low name ID."
