Recent polling averages show Democratic challenger Bob Brooks leading Republican incumbent Ryan Mackenzie by roughly four to six points among likely voters in Pennsylvania’s 7th district, a swing seat that favored Republicans by a narrow margin in 2024. The consistent edge aligns with trader pricing that places the highest probabilities on a Democratic victory margin between three and nine points. Key drivers include Brooks’s union backing and strength among women and independents, alongside the broader midterm environment and Democratic Governor Josh Shapiro’s sizable lead in the same district. The race remains competitive due to its partisan balance, high spending on negative advertising, and voter emphasis on cost-of-living issues that have not yet produced a decisive break. Late shifts in turnout or final-week developments could still alter the outcome before November 3.
