Pennsylvania primaries 2024: Lee and Fitzpatrick survive, matchups set for November

538 tracked congressional and downballot primary races in the Keystone State.

Pennsylvania is already in the thick of campaign season for November's presidential and U.S. Senate races, but on April 23, Democrats and Republicans in the Keystone State chose their candidates in a slate of other consequential races down the ballot this fall.

Among the key races to watch: a couple of incumbent House members — progressive Democrat Summer Lee and moderate Republican Brian Fitzpatrick — both fended off challengers from their right, and ballots are now set for a few other consequential contests that could help determine control of the House next year. Plus, some key battle lines for control of the state government in November are set, with the parties finalizing their candidates for attorney general, auditor, treasurer and both chambers of the state legislature.

Republican Jeffrey Olsommer on track to win Pennsylvania's only special election

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.

Only one contested U.S. House Democratic primary is still unprojected

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.

Checking in on candidates of color

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.

Mackenzie projected to win PA-07 and take on Rep. Susan Wild

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.

But PA-01 may be a tighter race this time around

That’s right, Meredith, and as I mentioned earlier, Fitzpatrick beat Ehasz by 10 points in 2022, but there are signs that this race could be tighter. It’s a purple district that has seen some shifts to the left, namely some recent school board elections. Voters flipped the Central Bucks School District from majority Republican to majority Democratic in an election last year, and Democrats swept the Pennridge School Board election. Of course, school board elections have their own quirks, particularly with some of the identity politics issues that have come to a head in recent years, but we could see a similar friction emerge with abortion as a hot-button issue in the general. While Fitzpatrick is hardly an anti-abortion activist, it’s an area where he hasn’t been as clearly moderate (he’s voted for abortion bans, for example, and his campaign website avoids the issue entirely), and Ehasz has a clear advantage on this front. Of course, Fitzpatrick’s incumbency and the more conservative reaches of the district could certainly be enough to keep him in his seat, but I’d be willing to bet it will be by a slimmer margin than last time, if he manages to pull it off.
