Glenn Thompson's retirement from Pennsylvania's solidly Republican 15th District, rated R+10 on the Cook Partisan Voter Index, anchors trader consensus at 90.5% odds for the GOP in the PA-15 House race, with state Rep. Ryan Mackenzie as the nominee holding a double-digit lead in his campaign's recent internal poll over Democrat Amanda Torres. District fundamentals, including Trump's 2020 margin exceeding 30 points, reinforce this edge amid a stable national House environment favoring incumbency-like continuity. Realistic challengers include a major Mackenzie scandal, unforeseen Democratic turnout surge in suburban areas, or polling underestimation of Torres's fundraising gains, though forecasters like Cook Political Report deem it "Likely Republican" with minimal volatility ahead of Election Day.
