In a significant electoral battle, Scott Perry, a hardline Republican, successfully retained his seat in a more moderate southern Pennsylvania district, defeating Democrat Janelle Stelson, a first-time candidate and former local TV news anchor.

This victory contributes to the GOP's regained majority in Pennsylvania's congressional delegation, now totaling 10 Republicans to 7 Democrats, reversing losses from 2018.

The races were among the most expensive in the nation, with over $35 million spent in the contest between Susan Wild and Ryan Mackenzie, and more than $31 million in the battle between Matt Cartwright and Rob Bresnahan.

Republicans also gained two additional U.S. House seats in eastern Pennsylvania, defeating incumbents Matt Cartwright and Susan Wild.

Both defeated Democrats had previously enjoyed narrow advantages in districts with Democratic registrations but faced well-funded Republican challengers.

The political landscape in the region has shifted significantly since 2016, with only five Democrats nationally running for reelection in Trump-won districts, highlighting the challenges they face.

Overall, these elections are seen as critical for the GOP as they prepare for potential challenges against Trump's second-term agenda.

The Republican victories are crucial as they help maintain the party's majority in the state's congressional delegation, a position they lost six years ago.

These wins come as Democrats aim to resist Donald Trump's second-term agenda amidst a precarious GOP House majority.

Perry's campaign was marked by controversy, as he is notable for having his cellphone seized by the FBI during investigations related to Trump loyalists, although he has not been charged with any crime.

In total, 14 other incumbents across Pennsylvania were reelected, maintaining a mix of party representation with both Democrats and Republicans securing their positions.

Perry's district showed a slight Republican registration advantage, although his hardline conservative stance does not fully reflect the local views.
