Incumbent Republican Glenn Thompson faces Democrat Ray Bilger in Pennsylvania's 15th congressional district, a solidly Republican seat with a Cook Partisan Voter Index around R+19 and consistent double-digit GOP presidential margins in recent cycles. Thompson, serving since 2009 and chair of the House Agriculture Committee, secured both party nominations unopposed in the May primaries, while Bilger's campaign has raised far less and lacks comparable name recognition or institutional support. With the November 3 general election three weeks away and no major new polling or campaign developments reported in the past month, trader consensus on Polymarket reflects the district's structural lean, pricing the most likely Republican margins in the 25-35 point range while assigning negligible probability to a Democratic upset. Limited turnout variability or late-cycle national shifts remain the primary variables that could narrow or widen the final spread.
