The field of candidates for November’s midterm elections in Allegheny County has largely taken shape. Primaries were held May 19 and independent and minor-party candidates have until Aug. 3 to file for ballot access.

All U.S. House seats, all Pennsylvania House seats and even-numbered Pennsylvania Senate seats are up for election this year. Each of those chambers is narrowly divided going into the November general election — Democrats control the state House while Republicans control the state Senate and U.S. House. 

Note: * denotes the incumbent. Write-in candidates and minor-party candidates will be added as information becomes available.

Democratic Gov. Josh Shapiro faced no competition from his party in his bid for a second term. He’ll face state Treasurer Stacy Garrity, who similarly had no Republican primary opponent, in November. 

Allegheny County’s own Austin Davis is Shapiro’s running mate as lieutenant governor again, and his fellow county resident Jason Richey received Garrity’s endorsement and the voters’ support for the Republican ticket.

Allegheny County’s two representatives in Congress are both Democrats running for third terms. 

Summer Lee will be opposed by Republican economist James Hayes in the Pittsburgh-based 12th District. Deluzio will run in the suburban-and-rural 17th District against Beaver County Sheriff Tony Guy.

Of Allegheny County’s 23 General Assembly seats on the ballot this year, 11 feature a contested general election after the primaries. More seats could join that list as the county tallies write-in votes for Republican primaries that had no names on the ballot.

All but one seat has an incumbent candidate. Only the 45th House District, in the western suburbs, is open, with Democratic Rep. Anita Kulik retiring. Democrat Brittany Bloam and Republican James Julius will vie for that seat.

The 45th and other suburban districts will be heavily scrutinized this fall as Democrats currently control the House by just one vote.
