Rep. Bill ShusterWilliam (Bill) Franklin ShusterSpending package extends FAA through September GOP leaders see finish line on omnibus deal Congress races to finish .2 trillion funding bill MORE (R-Pa.) has won his primary, beating back two conservative challengers.

The Associated Press has called the race for Shuster, who had 53 percent of the vote to Tea Party candidate Art Halvorson's (R) 35 percent and farmer Travis Schooley's (R) 11 percent with 86 percent of precincts reporting.

Shuster, the powerful chairman of the House Transportation Committee, won the race after working hard to shore up his right flank.

Halvorson had the backing of the conservative Madison Project, but big-spending national conservative groups didn't invest much in defeating the chairman.

Establishment Democrats also got their preferred candidate to face Rep. Mike Fitzpatrick (R-Pa.), as Army veteran Kevin Strouse (D) edged businesswoman Shaughnessy Naughton (D).
