WASHINGTON — The latest survey of the U.S. Senate race from Texas Public Opinion Research shows Democrat James Talarico leading Republican Ken Paxton, 45% to 40%, marking the Austin state representative’s largest lead in any public poll taken during the general election period.Since Paxton locked up the GOP nomination in late May, polling of the contest has found a neck-and-neck race with neither candidate able to break 50%. But TPOR’s poll found Talarico leading among voters who do not have a college degree — a group that has consistently favored Republicans in Texas and across the country — and dominating among independents, less than a quarter of whom said they planned to vote for Paxton. The attorney general also had weaker Republican support than in other recent surveys, with nearly one in five GOP voters saying they were undecided or would vote for Talarico.TPOR labels itself as a nonpartisan public opinion research group. It is directed by Democratic strategist Luke Warford.The group surveyed 1,048 likely voters between July 15 and July 17, and has a margin of error of +/- 3.4 percentage points. Of those poll respondents, 53% voted for Donald Trump and 42% voted for Kamala Harris in 2024, making the sample only slightly bluer than the 2024 electorate, which favored Trump by a 14-point margin in Texas. Trump carried Texas by 5.6 percentage points in 2020, two years after the last midterm held during his presidency.TPOR’s previous poll, fielded just after the May 26 runoff in which Paxton defeated Sen. John Cornyn, found Talarico leading 47% to 44%.Texas’ U.S. Senate race figures to be one of the most closely watched and expensive contests in the nation. Democrats have not won a statewide race in the Lone Star State in over 30 years, but they believe a combination of Trump’s lagging approval ratings, Paxton’s ethical baggage and Talarico’s fundraising and populist messaging could deliver the victory that has eluded them for decades.Republicans are taking the threat of Talarico seriously but nevertheless believe that, as the bitter primary between Paxton and Cornyn fades from memory and they highlight Talarico’s progressive views on social issues, Republicans will coalesce behind the attorney general. The nonpartisan Cook Political Report rates the race as “Lean Republican.”Paxton’s 40% vote share is the lowest he has received in a public poll post-runoff. Other surveys have found Republicans were consolidating behind him. But the TPOR poll had Talarico winning 7% of self-described Republicans, and an additional 12% remained undecided. Meanwhile, only 1% of self-identified Democrats indicated they would vote for Paxton, and 6% were undecided.For comparison, a New York Times/Siena poll of the Texas contest fielded in June, which found the overall result tied at 47%, found Talarico winning 5% of Republicans and only 4% unsure.Perhaps the biggest outlier was Talarico’s lead among non-college-educated voters, who favored the Democrat by nine percentage points — 45% to 36%. He led by 1 percentage point among those with at least a bachelor’s degree.In recent elections, education has been one of the most reliable predictors of how people vote, with a sharp partisan dividing line between those with and without degrees. Exit polling found that Republican Sen. Ted Cruz beat Democrat Colin Allred by 18 percentage points among non-college-educated Texans in 2024. Even in 2018, when Democrat Beto O’Rouke came within 3 percentage points of victory, Cruz still won that bloc by a 6-point margin, exit polls found.In the New York Times/Siena poll, Paxton had an 8-point lead among voters without a degree, and in TPOR’s own poll in May, Paxton led by a whopping 21 points among that group.Other results hewed closer to recent polling of the race. The TPOR poll found Talarico leading heavily among Black and Latino voters, while Paxton maintained a strong lead with white voters. Black voters broke 71% for Talarico and 8% for Paxton, while Latinos preferred Talarico by a 66% to 20% margin.Paxton led among white voters, 53% to 33%.Talarico’s polling lead owes to his strength with independents and non-college educated voters. The poll found Talarico garnering 43% of independents to Paxton’s 23%; 29% remain undecided. Among self-described moderates, Talarico’s lead is even more pronounced, with the Democrat ahead 54% to 20%.The poll found that 14% of voters of all political stripes remain unsure about their pick. Among undecided voters, there is evidence Paxton has more room to grow: 19% of that bloc said they leaned toward the Republican, compared to 10% who leaned toward Talarico. Two-thirds reported being truly on the fence.Some conservatives have cast doubt on the validity of TPOR's polling given its Democratic ties.
