Democratic candidates hold an edge across four key Pennsylvania House races, new polling shows. Democrats currently lead in two districts, hold a narrow advantage in a third, and are tied in the fourth. These contests serve as critical battlegrounds that could decide which party controls the narrow House majority soon.

Democratic candidates are ahead in two, hold a narrow edge in a third and are tied in a fourth, new polling shows. The seats embody the fights playing out nationwide in the midterms.

Democrats trying to unseat Republicans in four battleground Pennsylvania House districts are ahead in two of them, hold a narrow edge in a third and are tied in a fourth, according to new polling from The New York Times, The Philadelphia Inquirer and Siena University.

The four seats in Pennsylvania are seen as critical examples of some of the fights playing out nationwide. The districts include working-class communities in the state's northeastern corner, growing towns with large Hispanic populations, a swing Philadelphia suburb and some more conservative parts of the center of the state.

In the 2024 election, Pennsylvania was one of the country's biggest battlegrounds, and Republicans romped nearly everywhere. President Trump carried the state en route to being re-elected, and it was the only state in the country where Republicans flipped two House seats.

But the new polls show that Democrats are now leading in their bid to flip back both of those districts.

Taken together, the findings in the races for the four seats amount to another warning sign for a Republican Party that is increasingly at risk of losing its narrow House majority.

In Pennsylvania's Eighth District, Representative Rob Bresnahan, a Republican, trails his Democratic challenger, Paige Cognetti, the Democratic mayor of Scranton, 46 percent to 51 percent. Ms. Cognetti and her supporters have run numerous ads accusing Mr. Bresnahan of profiting from insider stock trading, and voters in Pennsylvania gave her an 11-point edge when asked which candidate they would trust to handle corruption.
