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.

One of the most competitive races today could be the Democratic contest for the open state attorney general, where Pennsylvania voters have a full slate of five candidates to pick from. It seems to be anyone's contest here, with each candidate bringing endorsements and support from different Democratic factions to the table.

The fundraising leader in this race is Northeast Philadelphia State Rep. Jared Solomon, a veteran who's emphasized anti-corruption and public safety on the campaign trail and in the state legislature. But his good-government bent hasn't seemed to win him friends in the party — he came in last in balloting for the Democratic Party endorsement (which no candidate ended up winning). The next biggest fundraising numbers came from Delaware County DA Jack Stollseimer and former Bucks County Solicitor Joe Khan, who previously served as a prosecutor in Philadelphia.

But there are two other candidates who may have other advantages in their pockets: The top vote-getter in the inconclusive party endorsement contest was Eugene DePasquale, who likely has a name recognition advantage. A Pittsburgh native, he represented York County as a state rep before winning statewide office as auditor general, and he's the only candidate from Western Pennsylvania. Meanwhile, the most progressive candidate in the race is likely Keir Bradford-Grey, a former chief public defender in both Montgomery County and Philadelphia. She's backed by the progressive Working Families Party and is looking to become the state's first Black AG, and the first AG in the country with a background primarily as a public defender. Her showing could tell us something about Pennsylvania Democrats' mood at a time when progressive prosecutors like Philadelphia DA Larry Krasner have come under increased scrutiny.

Whoever wins will be gearing up for a competitive general election, where they'll face the winner of today's GOP primary between York County DA David Sunday, who has his party's endorsement, and state Rep. Craig Williams, another veteran who represents parts of Chester and Delaware Counties and served as the chamber's impeachment manager against Krasner last year.

Further down the ballot, Democrats are also choosing their candidates today to challenge incumbent Republicans for two other statewide posts. In the Democratic primary for auditor general, the state's top fiscal watchdog, progressive Philadelphia state Rep. Malcolm Kenyatta earned the party nod, and is likely favored over Lehigh County Controller Mark Pinsley. For state treasurer, Erie state Rep. Ryan Bizzarro is similarly favored over Pittsburgh-area small business owner Erin McClelland. These races are expected to be highly competitive in November too: They were each decided by just a few percentage points in 2020, and Democrats have set their sights on reversing the results this time around.
