In the 139th state House District special election tonight, the only special for state legislative seats of the evening, Jeffrey Olsommer is on track to hold the seat for his party after former state Rep. Joe Adams resigned in February due to health concerns. Olsommer currently leads Democrat Roberta Skibber by about 6 percentage points, a margin that will likely grow as more election day votes are counted, according to the state election returns site. However, he does appear on track for an underperformance in this seat that Trump won by 28 points in 2020.

The 14th District in southwest Pennsylvania is a solidly Republican seat, but incumbent GOP Rep. Guy Reschenthaler will have an opponent in November. The question is, who? With 96 percent of the expected vote reporting, Navy veteran Chris Dziados leads business owner Ken Bach 54 percent to 46 percent in the Democratic primary. This makes Dziados a pretty clear favorite to win his party's nomination at this point, although the race is unprojected at this time.

All of today's congressional primary contests where nonwhite candidates were running have been projected, according to reporting by ABC News. Incumbent Reps. Dwight Evans and Summer Lee successfully fended off primary challengers, while Shamaine Daniels and Blake Lynch were both defeated by Janelle Stelson in a crowded Democratic primary for Pennsylvania's 10th. On the GOP side of things, only one candidate of color was running in a contested primary race tonight: Maria Montero lost to state Rep. Ryan Mackenzie in the 7th District, which Republicans have been eyeing as a potential flip this November.

And now we have a projection! ABC News reports state Rep. Ryan Mackenzie is projected to win the Republican primary race in the 7th Congressional District, setting him up to square off against Democratic Rep. Susan Wild in this highly contested district in Lehigh Valley this fall.

In tonight's primaries, voters aren't just deciding on federal candidates for November's general election; they're also setting up the battles for control of the state House and Senate. In 2022, Democrats won the governorship, and they currently hold a one-vote majority in the House they've struggled to maintain through a series of special elections. The party is looking to expand that House majority and gain control of the Senate for a trifecta by targeting opportunities (and defending some vulnerable seats) in the purple areas of this purple state. And, of course, Republicans want to keep their Senate majority, which they've held for 30 years, and take back the House.

Republicans have a six-vote majority in the state Senate, so Democrats need to pick up at least three seats for a tie, which could be broken by Democratic Lt. Gov. Austin Davis. Half the chamber is up for election this cycle. Among the handful of key races, Democrats will be defending an Allegheny County seat and challenging Republicans for a Harrisburg-based seat that are both opening up because of retirements. In both districts, each party is holding a contested primary today and redistricting could give Democrats a boost in November. Democrats are also challenging Republican incumbents in two seats that flipped to red in 2016 and 2020; one will hold a competitive Democratic primary today between Erie County Democratic Party Chair Jim Wertz and former Sen. John Fetterman staffer Selena King.

In the House, the hot primary action will largely be on the Democratic side, as the party's more progressive and centrist flanks face off in districts around Philadelphia and Pittsburgh. In West Philadelphia, Rep. Amen Brown is defending his seat against two challengers, Sajda Blackwell, whose family has a history in area politics, and progressive community activist Cass Green. Brown ran unsuccessfully for mayor on a tough-on-crime stance, and has sided with Republicans in criticizing progressive Philly DA Larry Krasner. Elsewhere in the city, three incumbents endorsed by progressive group Reclaim Philadelphia are facing challengers of their own. And in the Pittsburgh area, state Rep. Abigail Salisbury, who stepped into U.S. Rep. Summer Lee's former seat, is facing a challenge from Ashley Comans, a progressive school board member who lost to Salisbury last year and is endorsed by Lee herself.

Tonight's results will have an effect on their party's chances to hold onto the state House majority in November, and also the direction the Democratic party may try to take should it seize a trifecta.
