The Texas Senate race between Democrat James Talarico and Republican Ken Paxton is only heating up after the GOP midterm convention in early September.

A new Sept. 13 SoCal Strategies poll showed Talarico now leads Paxton 50% to 45%, a 5-point margin.

The poll surveyed 649 likely voters from Sept. 12-13 and showed a flip from SoCal's June poll, which had Paxton leading by 2 points.

Here's a breakdown of the poll's findings and how it compares with other polls.

The SoCal September poll showed that Talarico's lead among independents grew from 10% to 45% and he is now picking up 12% of Republicans. Talarico has also expanded his advantage with Hispanic voters from 10% to 38%, and voters aged 18-29 also back Talarico by 46%.

Meanwhile, Paxton has maintained most of his lead among white voters.

The interior of the American Airlines Center is seen on the first day of the 2026 Republican National Convention on Sept. 9, 2026 in Dallas, Texas. Republicans are kicking off two days of political pageantry aimed at blunting Democrats' momentum in the battle for control of Congress, holding their first-ever midterm election convention ‒ headlined tonight by President Donald Trump ‒ in a bid to boost GOP enthusiasm amid warning signs for the party. Trump is rallying Republicans for the final push toward the Nov. 3 election with a big show in the Lone Star State featuring a long list of party leaders and candidates in swing districts.

The president's approval rating has sagged as the Iran war drags on and cost-of-living concerns remain top of mind for many voters, threatening to weigh down GOP candidates. Trump has turned to the mini-convention to provide a boostas the party struggles to sell his second-term agenda.

But the poll also noted that while Talarico is polling at 50%, some evidence suggests the margin could tighten — much like the last poll, as Republicans are less decided than Democrats.

For example, while 6% of respondents who backed Donald Trump in 2024 are currently undecided in the Texas Senate race, only 1% of those who say they voted for Kamala Harris are undecided.

"To have a chance, Paxton will need to win nearly all of these voters and peel back a substantial portion of the 12% of Republicans who say they would vote for Talarico if the election were held today," the poll analysis stated.

This is the latest poll in September as the election cycle enters its final stretch to Election Day on Nov. 3.

An AARP poll on Sept. 10 showed Talarico with a 48% to 44% lead over Paxton, while an N+ Univision Sept. 9 poll showed Talarico with an edge at 48% to 43% in the Texas Senate race.

These three polls follow an August full of polls that showed the race between the two had been within the single digits:

Texas Public Opinion Research (Aug. 27) — Talarico 48%, Paxton 42%.

University of Texas/Texas Politics Project (Aug. 25) — Talarico 42%, Paxton 39%.

Emerson College Polling/Nexstar Media (Aug. 13) — Paxton 47%, Talarico 46%.

Texas Pulse/Texas A&M Bush School (Aug. 7) — Talarico 47%, Paxton 43%.

Texas Southern University (Aug. 4) — Talarico 47%, Paxton 45%.
