Recent polling in Pennsylvania’s 7th Congressional District shows Democrat Bob Brooks holding a narrow lead over Republican incumbent Ryan Mackenzie, with a Franklin & Marshall survey from mid-September placing Brooks at 45% to Mackenzie’s 40% among registered voters. The race centers on the competitive Lehigh Valley district that Mackenzie flipped by a slim margin in 2024, and forecasters rate it a toss-up or lean Democratic. Economic concerns, including affordability and personal finances, rank as top voter issues and appear to favor the challenger, a firefighters’ union leader who won a contested May primary. Low approval for the national Republican environment has contributed to trader consensus assigning Brooks an elevated implied probability ahead of the November 3 general election.
