Rep. Jim Gerlach (R-Pa.) has ended his campaign for Pennsylvania governor, clearing the way for state Attorney General Tom Corbett in the GOP primary.

In a statement, Gerlach said he wasn't able to raise enough money.

"While we have successfully raised over $1 million, traveled thousands of miles all across this Commonwealth and signed up more than 19,000 supporters eager to help us win, today's media-driven campaigns require four times that amount to wage a successful primary," he said.

Gerlach did not address whether he will instead seek reelection, which suggests it is on the table. A number of GOP candidates have stepped forward to replace him in a swing district.

But he did say that he intends to stay in politics beyond 2010.

"I want to be clear about one thing: this campaign for governor has stoked my passion for honest, effective, and efficient government, and I intend to continue to raise my voice, and work hard in the months and years ahead," he said.

Corbett was the GOP favorite and is expected to be a formidable candidate in the general election. Republicans will be happy to have a clear primary while a series of Democrats battle it out.
