Sen. Bob Casey (D-PA) has told the Hill that he will not be challenging current Pennsylvania governor Tom Corbett in 2014. The Senator had previously said at a Democratic event in New York that he was keeping all options on the table. Governor Corbett is up for re-election in 2014, and may be vulnerable. According to a poll from Public Policy Polling, he trails a generic Democrat 47% to 37%. His approval ratings have also hovered in the thirties. Sen. Casey was re-elected this year, fighting off self-made millionaire Tom Smith, and he may not want to get back into the campaign mode just yet. If Sen. Casey were to run, it would not be his first. In 2002 then-Auditor General Casey ran for governor. However, he was defeated in the primary by Ed Rendell, who went on to serve two terms.
