The competitive PA-07 race in the Lehigh Valley features Democratic challenger Bob Brooks, a former Bethlehem firefighter and union leader who won his May primary, against Republican incumbent Ryan Mackenzie, who narrowly flipped the seat in 2024. Recent polling averages show Brooks ahead by low single digits in this toss-up district that Donald Trump carried by less than a point last cycle, supporting traders' view of Brooks as the favorite. Mackenzie maintains a cash-on-hand advantage and has drawn high-profile GOP support, including from House Speaker Mike Johnson, while highlighting policy contrasts on taxes and energy. Brooks settled a personal lawsuit days before the September 13 market snapshot, potentially blunting opposition attacks. The outcome remains sensitive to national midterm dynamics and late-cycle spending in this key battleground for House control.
