(AP) Three Republicans will vie for the right to face Democratic U.S. Rep. Matt Cartwright in the race to represent Scranton, Wilkes-Barre, Pittston and neighboring areas in Congress.

Bethlehem Township sports car racing team owner Matt Connolly joined Schuylkill County Coroner David J. Moylan of South Manheim Township and Wind Gap airplane pilot Matthew Dietz in filing Republican nomination petitions by the state deadline Tuesday.The winner of the May 20 primary election would likely face Cartwright in the Nov. 4 general election. Cartwright, a Moosic resident seeking a second term, is unopposed for his party's nomination.He represents the 17th Congressional District, which also includes other parts of Lackawanna and Luzerne counties, all of Schuylkill County and parts of Carbon, Monroe and Northampton counties. Wind Gap and Bethlehem Township are part of Northampton County.Candidates for governor, lieutenant governor, state House and Senate and the other local congressional seats also filed to run.The candidates listed here are based on a list on the state Department of State website as of 8:30 p.m. Others who filed late in the day but before the 5 p.m. deadline might not have made the website list in time for this story.Several contested races emerged Tuesday as previously unannounced candidates filed petitions.In the other local congressional races, the contests will be largely as expected.In the 10th district, incumbent Republican Rep. Tom Marino of Lycoming Township in Lycoming County is unchallenged for renomination, but will likely face Democrat Scott Brion, an oil and gas industry investor from Jackson Township in Lycoming County in November. Nick Troiano of Milford, who bills himself as a civic entrepreneur, is working on running an independent candidacy for the seat, but independent petitions aren't due until Aug. 1.In the 11th, incumbent Republican Rep. Lou Barletta of Hazleton is also unchallenged for renomination, and would likely face civil rights lawyer Andrew Ostrowski of Susquehanna Township in Dauphin County.For governor, incumbent Gov. Tom Corbett found out he will have primary opposition from a frequent critic, Ardmore businessman Bob Guzzardi. Guzzardi argues Corbett violated his 2010 no-new-taxes pledge by increasing taxes on gasoline and authorizing new fees on natural-gas drilling, according to the Associated Press.The Democratic field narrowed Tuesday as Lebanon County Commissioner Jo Ellen Litz abandoned her longshot campaign, saying she couldn't meet the petition signature requirements, according to the AP.Six Democrats did file for governor: York businessman Tom Wolf, state Treasurer Rob McCord, U.S. Rep. Allyson Schwartz, former state environmental protection secretaries Katie McGinty and John Hanger and former state Auditor General Jack Wagner.For lieutenant governor, six Democratic candidates filed: Jay Paterno, son of the late Penn State football coach Joe Paterno, former U.S. Rep. Mark Critz, Harrisburg City Councilman Brad Koplinski, state Sen. Mike Stack, state Rep. Brandon Neuman and Bradford County Commissioner Mark Smith.Incumbent Lt. Gov. Jim Cawley was the only Republican candidate to file.bkrawczeniuk@timesshamrock.com
