Democrat Bob Brooks holds a clear edge over incumbent Republican Ryan Mackenzie in Pennsylvania’s 7th Congressional District, a Lehigh Valley swing seat that Trump carried by under one point in 2024. Brooks, president of the Pennsylvania Professional Fire Fighters Association, secured the Democratic nomination in the May primary and leads recent head-to-head polling by four points. Forecasters rate the race a toss-up or lean Democratic, citing the district’s narrow partisan balance, union strength in Bethlehem, and the broader 2026 midterm environment where the opposition party typically gains ground. Heavy outside spending and Mackenzie’s narrow 2024 victory keep the contest sensitive to turnout and national conditions through November.
