Pennsylvania has not seen the redistricting drama in some other states due to the divided control — with Republicans holding the majority in the Senate and Democrats holding the House and governor’s mansion.

Tuesday’s primary could be both dramatic and consequential all the same.

But voters on Tuesday will decide who will be on the ballot in several key races that could determine control of the U.S. House of Representatives.

Republicans hold a 217-212 majority in the U.S. House with five vacancies and one independent.

Democrats are competing in four contested primaries for the opportunity to run or hold seats in Congress. Three of the contested primaries are in districts where Democrats have targeted Republican incumbents considered vulnerable in the midterms.

Democrats have also targeted the 8th District, represented by first-term incumbent Rep. Rob Bresnahan, R-Luzerne. His presumed opponent, Scranton Mayor Paige Cognetti, is unopposed in the primary, but both candidates have begun banking up the campaign funds in a sign of how intense that race could be. On the other hand, two Republicans are competing for the chance to unseat two-term incumbent Democrat Rep. Chris Deluzio, D-Allegheny, in the 17th District.

In addition, Rep. Dwight Evans’, D-Philadelphia, retirement has attracted a crowded field of Democrats interested in running for the 3rd District seat in the fall.

1st District

Two Democrats — Bucks County commissioner Bob Harvie and Lucia Simonelli, a climate science researcher — are vying to challenge incumbent Rep. Brian Fitzpatrick, R-Bucks, in the 1st District, won by Kamala Harris in 2024.

Gov. Josh Shapiro on Monday endorsed Harvie in this race.

Harvie has outspent Simonelli by a factor of more than 20 to 1. Through April 29, Harvie had spent $850,000 on political advertising and had $604,000 in cash on hand. Simonelli reported spending $36,000 and had $35,000 in cash on hand.

3rd District

There is a four-way race in the Democratic primary in the 3rd District. No Republican is on the ballot. Two state lawmakers — Sen. Sharif Street, D-Philadelphia, and Rep. Chris Rabb, D-Philadelphia — along with pediatric surgeon Ala Stanford and attorney Shaun Griffith are running to fill the open seat.

Street and Rabb have led the way in campaign spending in the race. Street had spent $895,000 and had $160,000 cash on hand through April 29. Rabb spent $628,000 and had $373,000 cash on hand.

Stanford had spent $535,000 and had $211,000 in cash on hand. Griffith had spent almost $12,000 and his campaign reported no cash on hand. Harris got 88% of the vote in the 3rd District in 2024 and there is no Republican on the ballot.

7th District

The race to nominate a candidate to try to unseat first-term incumbent Rep. Ryan Mackenzie, R-Lehigh, has also attracted a four-way fight among Democrats. Trump won the district with 50.6% of the vote in 2024. Mackenzie got 50.5% of the vote to defeat incumbent Democratic Rep. Susan Wild.

The Democratic primary will feature Bob Brooks, the president of the Pennsylvania Professional Firefighters Association; former federal prosecutor Ryan Crosswell; former Northampton County executive Lamont McClure; and Carol Obando-Derstine, former regional manager and statewide Latino affairs advisor for former U.S. Sen. Bob Casey.

Through April 29, Brooks spent almost $920,000 and had $252,000 in cash.

Crosswell spent $1.3 million and had $437,000 in cash on hand. McClure spent $370,000 and had $142,000 in cash, while Obando-Derstine reported having spent $470,000 and had $95,000 in cash on hand.

8th District

While Cognetti has no primary opposition, she has already spent more than $832,000 on the campaign. Her campaign reported having $2.25 million in cash on hand.

Bresnahan had spent just under $2.3 million through April 29 and his campaign reported having $2.27 million in cash on hand.

Bresnahan defeated Rep. Matt Cartwright, an eight-term incumbent in 2024. Bresnahan got 50.8% of the vote in a district Trump won with 53.6% of the vote.

10th District

Two Democrats are vying for the opportunity to challenge seven-term incumbent Rep. Scott Perry, R-Cumberland. Former TV news reporter Janelle Stelson, who lost to Perry 50.63% to 49.37% in 2024, is running for the chance to try to oust Perry again. She faces Dauphin County Commissioner Justin Douglas in the Democratic primary.

Stelson spent $1.33 million and reported having $3.35 million in cash on hand.

Douglas spent almost $128,000 through April 29 and reported having $10,600 cash on hand.

Trump won the 10th District with just under 52% of the vote in 2024.

Perry has spent $2.15 million and reported a campaign war chest of $2.34 million.

17th District

Republicans only have one contested primary in a congressional race — in the 17th District where Jesse James Vodvarka, a manger in his family’s springs and wire forms factory, and Beaver County Sheriff Tony Guy are competing to determine who will face incumbent Rep. Chris Deluzio, a Democrat who was first elected in 2022 and won re-election in 2024.

Guy reported spending almost $12,000 and his campaign had $43,000 in cash through April 29. Vodvarka had spent just over $7,000 and his campaign reported having just under $3,000 in cash on hand, as of April 29.

Even though Deluzio is unopposed in the primary, his campaign reported spending $1.76 million through April 29, with $923,000 in cash on hand.
