Recent September polling averages show Democrat James Talarico holding narrow leads or statistical ties against Republican Ken Paxton in the Texas U.S. Senate race, with most surveys placing the margin inside three points among likely voters. The contest remains rated a toss-up by major forecasters after Paxton defeated incumbent John Cornyn in the May Republican primary runoff. Persistent demographic divides, strong independent support for Talarico, and heavy late-cycle advertising from both national parties sustain the tight positioning. Traders assign comparable probabilities to small victory margins for either candidate, reflecting uncertainty over final turnout, undecided voters, and any last-minute developments before the November 3 election.
