The 2026 Election Season Kicks Off: A Preview of the 2026 Texas Senate Primary

After a long wait, the 2026 midterms season wewill be kicked off by two riveting races in one of the most interesting – and, to a certain extent, puzzling – states in the nation when voters in Texas will head to the polls on March 3rd.

Both Democrats and Republicans in the Lone Star State will be called to an arduous but consequential decision over who to send to square it off in the November general election in a race that does have the potential of becoming a bell-weather as to which party will hold control of Congress’ upper chamber in the last two years of the Trump Presidency. 

If that wasn’t good enough, both US Senate primaries are bound to highlight ideological fault lines inside the parties, potentially offering clues over the broader direction the GOP and Democrats will take in the near future.

An Ever-Evolving State

Texas’s profound demographic changes have widely shaped its political dynamics. Once a white-majority state with a wide rural population and well-off suburbs, the Lone Star State has remained a GOP stronghold for much of the last 50 years, nurturing traditional Republican stars like former Presidents George H. W. Bush and George W. Bush – both hailing from the Houston metro area. 

Still, Texas’ racial and social makeup underwent a monumental change compared to the beginning of the 21st Century, transitioning from a White-majority to a Hispanic-plurality state, with Hispanics making up more than 40% of its population in the latest US Census surveys. On top of that, the overall population boomed, as Texas gained 10 million residents in less than 25 years, a 50% increase that far outpaces the 17% spike in US residents over the same span of time – and is reflected in the Lone Star State gaining 6 electoral votes after the 2020 Census compared to the 2000 election, with another increase in its electoral weight in sight ahead of 2030.

Texas’ diversification and fast growing population means Democrats were able to close to gap to the GOP in recent years, setting their sights on eventually flipping a red bastion worth 40 EVs. While the state only narrowly trails the US as a whole in terms of Median House Income and share of population that attained a college degree – two parameters that have increasingly been associated with Democratic leaning – it was Texas’s growing Hispanic population and growing suburbs – coupled with the progressive extinction of the traditional GOP brand – that propelled a remarkable leftwards swing in the latter part of the 2010s. Former President Joe Biden came just 6 points short of flipping a state that last voted for a Democratic presidential nominee in 1976, when Jimmy Carter defeated incumbent Republican Gerald Ford. 

But while Trump’s struggle with highly-educated suburban voters was not significantly reversed in 2024, he was able to make significant gains among the Hispanic population, in particular with working-class Hispanic men. All of a sudden, as Democrats keep making inroads into well-off, White voters, Texas’s high diversity turned from a source of hope into a vulnerability, as Trump carried the state by a whopping 14.7-point margin, marking a 8% rightward swing compared to 4 years later.

Still, it’s uncertain whether Republican gains amongst Latinos will stick into future contests, particularly when Trump’s penchant for mobilizing low-propensity voters will be affected by his absence on the ballots. While the Hispanic community seems to think positively of Trump’s operation against former Venezuela dictator Nicolas Maduro, the persisting issues of inflation and the cost of living as well as the administration’s unyielding focus on deportation threaten to disrupt Trump’s gains among a community particularly affected by both the cost of living and  the ongoing immigration enforcement operation.

It’s unclear how much a more traditional Republican like Cornyn or a conservative firebrand the likes of Paxton may move the Hispanic community, while both Crocket, with a record of representing a highly diverse district, and Talarico, who may appeal to rural, deeply religious Hispanic communities concerned with the cost of living, have a chance at walking back the Democrats slippage with such a crucial chunk of the electorate, even though the extent of the 2020 to 2024 movement was historic.

Texas is still right of the nation

On top of that, we ought to think about the rightward shift the Lone Star State registered a little more than one year ago in the broader context of the 2024 election. Compared to 2020, the US as a whole shifted 6 points to the right: as a consequence, Texas voting 13 points to the right of the nation was just a 3% increase compared to 2020, and still a far cry from the 20-point difference registered between the late 2000s and the early 2010s.

Under this light, Texas’s 8-point lean should be for a good part ascribed to a positive national environment for the GOP, rather than just to isolated dynamics among the Hispanic community. In fact, while the Latino electorate provided Trump with a sizable boost, the President did struggle with another key group: high-income, college-educated suburban voters.

From Dallas to Houston through the Texas corridor between Austin and San Antonio, the higher the income and the higher the share of White population, the lower the President’s improvement over his 2020 was. Most worryingly for the GOP, the Dallas and Houston metro areas registered an original trend in 2024: Democrats fared better in high-income, low-educational attainment communities, while top high-income, high-educational attainment counties swung more to the right. The behavior observed in these areas differs from what has been witnessed in other areas of the country, where Trump did retain some strength among the very rich but struggled with the top 1% of college-educated voters – as shown by U-shaped trend lines when plotting – and is an omen for the GOP as it shows leakage even among upper-middle class voters with medium level of educational attainment.

Whether a progressive, divisive figure such as Crocket can maintain or expand Democrats’ inroad in suburbia remains to be seen, even though it stand to reason to think that high-income voters would  be equally put off by a scandal-ridden candidate like Attorney General Paxton. Talarico’s economic populism may as well not be the best recipe to capitalize on a group that has been shifting hard to the left during Trump’s era, but his moderate persona could tamp down the potential effect of his  “Top vs. Bottom” rhetoric. 

Can Cornyn hold the suburbs?

On the other hand, John Cornyn is the epitome of a suburban powerhouse. While he may struggle in rural, White areas, where Trump himself did not extract major gains in 2024, particularly against Talarico, and among Hispanic voters, he would be all but certain to at least limit the GOP bleeding in major suburbs. The latest time he was re-elected in 2020, when he ran four points ahead of Trump, his overperformance came entirely from urban and exurban counties. In particular, Cornyn trounced Trump in the high-income and high-education communities around Dallas, Houston, Austin and San Antonio.

This makes sense: the progressive leftward swing of America’s upper middle first involved the highly-educated, as seen in 2020, and, subsequently, also included well-to-do voters with slightly lower level of educational attainment. If Cornyn wins the GOP nomination, he has a chance at not only winning back – or reducing the loss with – portions of the highly-educated electorate, but also high-income voters, exploiting the latter’s group growing aversion to MAGA Republicans against Paxton, who will probably find his base in rural communities.

Finally, while Cornyn outperformed Trump in inner cities back in 2020, and will in all likelihood outrun his rivals there in the primary, he may find a remarkable adversary in Crockett should they square off in the general election. The US Representative is highly attached to her downtown community, and is expected to have the edge against Talarico with minority, urban vote.

The Polls and the Odds

For what concerns the general election, even in midterm years and considering down-ballot races, Texas has a solid track record of voting to the right of the nation. Still, the gap has narrowed in the latest years, going from R+11 in 2018, when Ted Cruz eked out a narrow re-election to the Senate despite Democrats winning the House popular vote by almost 9 points, to R+8 in 2022 and R+7 in 2024, as Cruz won comfortably while Trump carried the national popular vote by 1.5%.

As a result, while Republicans couldn’t be but the favorite to retain the seat, Democrats can in fact see a path forward, in particular if certain conditions are met. With today’s political polarization, it is unlikely we will witness a 2018-level popular vote margin, but even a D+5 victory, as suggested by DDHQ Congressional Generic Ballot Polling Average may do the trick. Should Democrats gain an edge in terms of candidate quality, for instance in case of Paxton winning the nomination, Democrats may indeed have a real chance of coming on top.

While Cornyn has been on average a solid candidate, outperforming generic Republicans in 3 out of the 4 times he ran for the Senate, a controversial candidate like Paxton may end up trailing the national GOP by a few points, giving Democrats a clear opportunity to eke out a 1-2% victory come November, even as Kalshi give them a roughly 1-in-4 chance of flipping the seat, which may give Democrats control of the Senate in the 120th Congress.
