Recent polling and shifting race ratings have positioned Democrat Bob Brooks as the clear favorite in Pennsylvania’s 7th congressional district. A September Franklin & Marshall survey showed Brooks leading incumbent Republican Ryan Mackenzie 45-40 among registered voters, with 16% undecided, while Cook Political Report moved the contest from toss-up to Lean Democratic on October 10. Mackenzie flipped the Lehigh Valley seat by roughly one point in 2024 in a district Donald Trump carried by under one point. Brooks, a former Bethlehem firefighter and union leader, secured strong Democratic endorsements and primary support after defeating multiple rivals. Traders appear to weigh these polling trends and the district’s competitive fundamentals more heavily than Mackenzie’s fundraising edge, producing the current implied probabilities.
