Democrat Bob Brooks Unseats Republican Ryan Mackenzie, Flips Pennsylvania’s 7th Congressional District

Democrat Bob Brooks won election to the U.S. House in Pennsylvania’s 7th Congressional District on Tuesday, November 3, 2026, defeating incumbent Republican Rep. Ryan Mackenzie, according to the Associated Press.

The Associated Press called the race at 10:27 p.m. Eastern Time on Election Day. With approximately 80% of the vote counted, Brooks had 57% of the vote, compared with Mackenzie’s 43%, according to AP results.

The result flips the Lehigh Valley congressional seat from Republican to Democratic control, giving Brooks his first term in Congress. The district includes Lehigh, Northampton and Carbon counties, along with part of Monroe County. Mackenzie had held the seat since January 2025, after narrowly defeating Democratic Rep. Susan Wild in 2024.

Brooks, a labor leader and former firefighter, campaigned on affordability, workers’ rights and protecting access to healthcare. His victory was part of a broader Democratic resurgence in Pennsylvania, where several Republican-held congressional districts flipped.

Mackenzie, a Lehigh Valley native and former Pennsylvania state representative, won the congressional seat in 2024 by narrowly defeating Democratic incumbent Susan Wild. During his first term, he supported President Donald Trump’s tax-cut legislation and immigration enforcement policies while promoting expanded child tax credits and border security.
