Will Democrat James Talarico defeat Ken Paxton in the 2026 Texas U.S. Senate race?

This race is a test of whether party loyalty beats candidate doubts. Paxton, the state attorney general, beat Sen. John Cornyn in a bruising primary runoff, and part of Cornyn's coalition has not come home. In the Texas Southern University poll only 84 percent of Republicans back Paxton, while 7 percent choose Talarico. Late-deciding Republicans usually return to their party, so the key question is how many of those holdouts stay away or cross over.

Talarico, a state representative, runs as a faith-forward Democrat aimed at suburban and younger voters, and the age split has held. Fox affiliates reported that in the YouGov poll fielded from late September into October, about two thirds of the youngest voters backed him while a majority of the oldest voters backed Paxton. Midterm electorates skew older, so his path still depends on unusual youth turnout.

Both campaigns are now managing a gap in the calendar. Talarico has been off the trail since September 30, which his campaign attributes to the flu, and Paxton has turned the absence into a rally line. Paxton, for his part, has declined or ignored repeated debate invitations. A favored candidate avoiding debates and a challenger avoiding the trail are both choices that cost little if the race is static and a lot if it is moving.

The reference class is Texas Senate races since 1990: Democrats lost all 13, and the last Democrat elected was Lloyd Bentsen in 1988. Big money has not broken the streak. Beto O'Rourke raised nearly $45 million more than Ted Cruz in 2018 and still lost by 2.6 points, and Colin Allred outraised Cruz by about $21 million in 2024 and lost by 8.5.

The closest analogue is O'Rourke in 2018, a charismatic Democrat against a polarizing Republican in a Trump midterm. The analogy breaks in three ways that favor Talarico: the national environment is now worse for Republicans than in 2018, the Republican nominee is struggling to unify his own party, and the seat is open, so no incumbent advantage protects the Republican.

Start from the Texas prior. Zero Democratic wins in thirteen tries since 1990, smoothed with the rule of succession, gives about 7 percent. That rate counts years in which no Republican nominee trailed in October polling, so it is weak evidence here, and we give the polls most of the weight. Version 1 started from a tied race and landed at 52 percent.

What changed since September 26: three polls fielded since then all show Talarico ahead. As reported by Fox affiliates and Newsweek, a Fox News poll fielded in late September had him up two, the New York Times and Siena poll released October 3 had him up six, fifty one to forty five, and a YouGov poll fielded into early October had him up six, fifty to forty four. Our calculation: the average lead across the three is about four point seven points. In this version we rebuild the number from that lead instead of stacking adjustments on version 1, because the national environment and Paxton's weak consolidation are already inside the polls.

Arithmetic, our calculation: take the four point seven point lead, subtract about 2 points for the Texas polling misses of 2020 and 2024 (counted once; in 2018 O'Rourke ran ahead of his polls, so we do not treat the miss as automatic) and about 1 point for undecided Republicans returning late, leaving an expected margin near one point seven points for Talarico. With an assumed polling error of about six and a half points for a Senate race three weeks out, that edge is about 0.26 standard deviations, or roughly a sixty percent win chance. Subtract about 1 point for Talarico's two weeks off the trail. That lands at 59 percent, below the market price, with a range of 47 to 70 percent because a normal polling error flips the result.
