Pennsylvania Gov. Tom Corbett on Wednesday announced he raised $6.8 million in 2013 and now has $7.5 million on hand for his re-election bid this year.

"Governor Corbett has kept his promises and made the tough decisions necessary to put our commonwealth back on the right track and put Pennsylvanians back to work," Corbett's campaign manager, Mike Barley, said in an email statement.

Corbett, who faces one of the toughest re-election bids in the country, has some of the worst approval ratings among incumbent governors. A Public Policy Polling poll from November showed the governor with a measly 24-percent approval rating. However, despite the governor's low approval numbers, his 2013 financial haul puts him in a competitive spot against his Democratic challengers.

Perceived Democratic front-runner Rep. Allyson Schwartz announced earlier this month that her camp raised $6.5 million in 2013, just $300,000 shy of what Corbett was able to pull it. Another Democratic challenger, former Pennsylvania Revenue Secretary Tom Wolf, announced he had raised $2.9 million and would be adding $10 million of his own money.

Corbett's campaign announcement touts how the Republican governor has raised $12.3 million since 2011, however it was in 2011 that he implemented statewide education cuts that he still hasn't been able to recover from in the polls. Just last Friday at an event in Philadelphia, Corbett defended those cuts.

"We have faced difficult challenges from the day I walked into office," Corbett said. "We had federal money that no longer existed in the K-12 budget." Still, that reasoning hasn't swayed voters who still disapprove of the governor by historic margins.
