A mere 24 percent of Pennyslvania voters approve of the job Corbett is doing while 65 percent said they disapprove, the worst numbers for any governor tested by PPP. It's so bad for Corbett that even a majority of in-state Republicans — 51 percent — disapprove of his job performance, according to PPP.
PPP also showed Corbett trailing all would-be Democratic challengers by 12-20 points.
Those numbers are nothing new for Corbett, who may be the most vulnerable incumbent governor heading into 2014. A poll released last month showed only 20 percent of voters believe he deserves re-election, while 67 percent said it's time for a change.
PPP found that 42 percent of GOP primary voters in Pennsylvania want Corbett to be the party's nominee next year, while 47 percent said they would prefer someone else.
