Denton County's suburban voters in the Dallas-Fort Worth metro area have made the U.S. Senate contest between Democrat James Talarico and Republican Ken Paxton unusually competitive, with trader consensus reflecting Talarico's modest edge. Recent polling averages show the statewide race within a few points, driven by Talarico's record fundraising—including in traditionally Republican ZIP codes—and his emphasis on education and cost-of-living issues that resonate in growing suburbs. Paxton's primary victory over incumbent John Cornyn secured the GOP nomination with Trump backing, yet ethics concerns have kept his favorability low among independents and suburbanites. A Trump appearance in Denton on October 1 and the start of early voting on October 19 could shift turnout patterns, while minor candidates and write-ins remain long shots in a two-party dominated county.
