Incumbent Republican Glenn Thompson faces Democrat Ray Bilger in Pennsylvania's 15th congressional district on November 3, 2026. The district's strong Republican lean, reflected in a Cook Partisan Voter Index around R+19 and Donald Trump's 21.5-point margin there in 2024, anchors trader consensus at 94.5% for the Republican nominee. Thompson, seeking a tenth term after unopposed primary advancement in May, benefits from consistent reelection history and stable nonpartisan ratings classifying the seat as Solid or Safe Republican. No competitive polling or notable developments have emerged since the primaries to shift positioning. A Democratic upset would require an unforeseen national environment or district-specific disruption capable of overcoming these structural barriers.
