**Bob Brooks leads the PA-07 House race in trader pricing due to recent polling momentum and Democratic structural advantages in the Lehigh Valley district.** A Franklin & Marshall poll conducted September 9–20 showed Brooks at 45% to incumbent Ryan Mackenzie’s 40% among registered voters, with 15% undecided. Brooks secured the Democratic nomination in the May 19 primary with strong backing from Gov. Josh Shapiro and labor unions, while Mackenzie advanced unopposed on the Republican side. The seat, rated a toss-up or lean Democratic by multiple forecasters, features heavy outside spending and national party focus as one of the more competitive House battlegrounds. Traders appear to weigh Brooks’ current polling edge and the district’s slight Democratic tilt more heavily than historical Republican performance in 2024.
