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.

The Lehigh Valley, around Allentown in eastern Pennsylvania, is the backdrop to what is set to be one of the most competitive House races in the state (and the nation) this fall: the 7th District. Democratic Rep. Susan Wild will be squaring off against one of three Republicans vying to challenge the three-term congresswoman. In 2022, Wild held onto her seat by just 2 points in this competitive district, and Republicans are hoping they can finally flip it. Razor-thin races like this will help determine if the GOP can maintain control of the House.

The three Republicans battling it out in the GOP primary are Kevin Dellicker, a consulting company owner who was the runner-up in the 2022 primary, attorney Maria Montero, and state Rep. Ryan Mackenzie, a local boy who has represented the region in the general assembly since 2012. Dellicker has outraised his opponents by about double, according to recent FEC filings, bringing in $447,000 to Mackenzie's $272,000 and Montero's $214,000. But Mackenzie has received substantial outside support to the tune of almost half a million dollars from Americans for Prosperity Action, a libertarian super PAC founded by the Koch brothers. There's no polling available for this race and not a ton of daylight between the three candidates when it comes to policy positions on hot-button issues like immigration, abortion and climate change, so it could be anyone's race. However, the heavy spending on Mackenzie's campaign and his local name recognition are distinct advantages.
