HARRISBURG — Gov. Tom Corbett said Monday that getting his fellow Republicans in the Legislature to agree on something is perhaps one of the most difficult jobs he’s ever had to do.

Corbett made the comments as he heads into his third year as governor and confronts major issues that are pressing on Pennsylvanians, including boosting transportation funding and scaling back public pension costs.

The Republican governor suggested during an appearance on a Pittsburgh radio station that Republican harmony is no small task after conservative show host Marty Griffin told Corbett that the “knock on you” is that Corbett hasn’t advanced key bills despite sharing power with a Republican-controlled Legislature.

“Just as there is a broad spectrum of Democrats from conservative Democrats to very liberal Democrats, so too does the Republican Party in the House and in the Senate here in Pennsylvania have moderate to liberal Republicans to conservative Republicans, and getting them all on the same page, working in the same direction is probably the most difficult job I’ve ever had to do,” Corbett said.

A spokesman for House Republicans said House and Senate GOP leaders did a tremendous job of reaching consensus and getting important legislation to the governor’s desk.

“This past legislative session was hugely successful and one of the most accomplished in recent memory, so frankly I’m not certain where that comment would come from,” said the spokesman, Steve Miskin.

The 2013-14 legislative session will begin in January, and Corbett will have fewer Republicans to win over: The Senate’s Republican majority is shrinking to 27 to 23, down from 30 to 20 after three victories in races for open seats by Democrats.

In his first two years, most of Corbett’s priorities that passed did so with little or no support from Democrats.
