Incumbent Republican Pat Fallon secured the GOP nomination in Texas's March 3 primary for the TX-04 House seat, facing Democrat Jason Pearce in the November general election. Traders price Republicans at 86% implied probability, reflecting the district's Solid Republican rating by Cook Political Report, even after 2025 redistricting that maintained its deep-red lean from Dallas suburbs to the Arkansas border. Fallon won prior cycles with double-digit margins, and no recent polling, fundraising gaps, or scandals have emerged to threaten GOP dominance in this low-turnout, conservative stronghold. Statewide generic ballot polls show tight races elsewhere, but TX-04's electoral math favors the incumbent amid stable voter blocs.
