Bob Brooks leads Republican incumbent Ryan Mackenzie in Pennsylvania’s 7th Congressional District, a competitive Lehigh Valley seat rated toss-up or lean Democratic by multiple forecasters ahead of the November 3 general election. A late-September Franklin & Marshall poll showed Brooks ahead 45-40 percent with 16 percent undecided, while broader polling averages and models project a narrow Democratic edge tied to voter concerns over the economy and independent support. Mackenzie’s reelection bid has featured personal attacks on his opponent alongside emphasis on tax relief and bipartisan work, but the race remains a key battleground for House control with limited recent shifts in public polling data. Trader consensus reflects these fundamentals through elevated probability for the Democratic nominee.
