Incumbent congressmen set sights on November with primary wins
Incumbents in four Western Pennsylvania congressional districts made it through Tuesday's primary unscathed. Here's a look at the races:
15th Congressional District
Indiana County sociology professor Susan Boser won the Democratic nomination to challenge Republican incumbent U.S. Rep. Glenn “GT” Thompson Jr. of Centre County in November, according to unofficial results.
Boser was leading Wade Jodun of Centre County by 49 percentage points with 95 percent of Pennsylvania's voting precincts reporting results about 11:40 p.m., unofficial tallies showed.
Thompson, who has served in Congress since 2009, was unopposed in the GOP primary.
The newly created 15th Congressional District includes Armstrong and Indiana counties, part of Butler County and all or part of 11 other counties.
16th Congressional District
Erie attorney Ron DiNicola defeated two rivals to earn the Democratic nomination to challenge U.S. Rep. Mike Kelly, R-Butler, in November, unofficial results showed.
DiNicola, 61, collected 60.2 percent of the votes counted, while neither of his two opponents mustered more than 25 percent.
Kelly, 70, was unopposed in the newly constituted 16th Congressional District that includes part of Butler County and Erie, Crawford, Mercer and Lawrence counties. Kelly has represented Pennsylvania's northwestern congressional district since 2011.
17th Congressional District
A highly anticipated matchup between incumbent U.S. Reps. Keith Rothfus, R-Sewickley, and Conor Lamb, D-Mt. Lebanon, now officially gets underway with the candidates securing their parties' nominations Tuesday.
Rothfus and Lamb were unopposed. The newly constituted 17th Congressional District includes Beaver County and parts of Allegheny and Butler counties.
Rothfus, 56, has represented parts of the district since taking office in 2013. Lamb, 33, won a special election in March to represent Pennsylvania's southwesternmost congressional district. Lamb's Mt. Lebanon was drawn out of that district when the state Supreme Court reconfigured Pennsylvania's congressional district boundaries early this year and placed it in the new 17th District.
18th Congressional District
U.S. Rep. Mike Doyle, D-Forest Hills, appears to be on his way to a 13th term in Congress.
Doyle, 64, defeated challenger Janis C. Brooks of North Versailles with 75.8 percent of the votes counted, compared with Brooks' 24.1 percent, unofficial results showed.
No Republicans sought their party's nomination to run against Doyle in November.
