Recent polling in Pennsylvania’s 7th Congressional District shows Democratic challenger Bob Brooks, a former firefighter union leader who won his May primary with broad party support, leading incumbent Republican Ryan Mackenzie 45-40% among registered voters, with 16% undecided. Low presidential approval ratings and economic concerns among district voters have contributed to the Democratic edge in this Lehigh Valley swing seat, which Republicans held narrowly in 2024. Heavy outside spending by both parties underscores its importance for House control. Trader pricing for Brooks reflects this momentum and historical midterm patterns favoring the opposition party, though the race remains within the margin of error and subject to shifts from undecided voters before the November 3 general election.
