Most of the state and U.S. elections this year will feature two or more candidates on the Butler County ballot.

Five of the seven incumbent state House representatives in the county — all Republicans — will likely each face challengers this year, as the field of candidates for the May 15 primary and Nov. 6 general elections are nearly set.

Here are incumbent state legislators and their challengers, according to the Department of State's website:

Tedd Nesbitt, R-8th, will face Democrat Lisa K. Boeving-Learned of Worth Township, Mercer County.

Aaron Bernstine, R-10th, will run uncontested after Democrat Joseph McGurk of Beaver Falls, Beaver County withdrew from the race last week, after a challenge to his petitions was filed.

Brian Ellis, R-11th, will not face a major-party challenger. But Sam Doctor of Butler Township has announced his candidacy as an independent. Independent and third-party candidates have until Aug. 1 to file nominating petitions.

Daryl Metcalfe, R-12th, will face the winner of a Democratic primary election between Honora Rockar of Cranberry Township and Daniel Smith Jr. of Adams Township. Smith on Thursday overcame a petition challenge.

Jim Marshall, R-14th, will face Democrat Amy Fazio of Daugherty Township, Beaver County.

Jeff Pyle, R-60th, will be uncontested after Democrat challenger Laurie Kubli of West Franklin Township, Armstrong County withdrew March 19, after a petition challenge was filed.

R. Lee James, R-64th, will face Democrat John Kluck of Oil City, who ran two years ago and got 37 percent of the vote in a three-way race.
