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.

Pennsylvanians will technically pick their nominees today for the state's U.S. Senate election this fall, though the results won't be a nail-biter — both major party candidates are running unopposed in their primaries. Democratic Sen. Bob Casey Jr. is running for a fourth term, while David McCormick, a former hedge fund CEO and diplomat under the Bush administration, is hoping to claim the seat for Republicans.

While today's primary isn't competitive, the general election matchup is already attracting a lot of attention. Democrats currently have just a one-seat majority in the Senate and are defending at least seven competitive seats this cycle, including Casey's in Pennsylvania. That means control of the chamber could come down to the Keystone State, a prospect that both parties are taking seriously.

Both candidates have already dropped millions of dollars on the race. While McCormick slightly outraised his opponent last quarter, Casey has spent over two and a half times as much money this cycle and has close to twice as much cash on hand as McCormick.

Casey also leads in every poll we've collected of the race, although some of those leads are within the margin of error. All the major election handicappers agree that he appears to have an edge in the race for now, though it's still competitive enough that things could easily change by November. Tonight won't be able to tell us much about the future, but it marks the official start to one of the most closely watched matchups this cycle.
