HOUSTON — No county in Texas holds more Latino residents than Harris County, home to an estimated 2.2 million Hispanic residents, or close to half the county's population. Yet on Election Day, that share hasn't translated into ballots: voters with Spanish surnames have historically made up only about one-fifth of votes cast here, according to figures kept by the Harris County Elections Office. That gap between population and turnout sits at the center of a question both parties are racing to answer before November — which side can convert a famously unpredictable electorate into a decisive one.
Most of the attention on Texas' Latino vote this cycle has gone 350 miles south, to the Rio Grande Valley, where Republicans posted historic gains in 2024. Harris County draws far less scrutiny by comparison — even though it may be the bigger prize.
A Question Raised in Austin
That tension played out in late July at the annual conference of UnidosUS, the nation's largest Hispanic advocacy organization, where more than a thousand people packed the Fairmont Austin. One question kept resurfacing across the panels: how Latino voters feel roughly two years after helping fuel Republican gains across Texas and the country.
During an economic discussion, attendees answered live polling questions on their phones, and a word cloud took shape on the screen showing what mattered most to the room. "Cost of living is the top concern," UnidosUS senior policy analyst Santiago Sueiro told the crowd — with jobs and wages close behind, ahead of both immigration and health care.
That framing carries particular weight in Houston. Harris County's Latino population skews younger and more working-class than the electorate overall, meaning affordability messaging may resonate differently here than in South Texas border communities, where immigration enforcement remains a more immediate, lived concern.
The National Swing, Revisited
Nationally, Donald Trump won roughly 48% of the Latino vote in 2024, according to a later, more rigorous Pew Research Center analysis of validated voter files, reported by Axios — notably higher than same-night exit polling suggested, which had put his share somewhere between 42% and 46% depending on the pollster. Texas outpaced that national shift by a wide margin. Exit polls found Trump captured 55% of the state's Latino vote, a result driven substantially by a historic realignment in the Rio Grande Valley, where Trump swept all four border counties in 2024 — including Starr County, a 97%-Latino county that had backed Democratic presidential candidates for well over a century before flipping to the GOP for the first time since 1896.
Less than two years later, some of that support appears to be softening — though not necessarily converting into Democratic votes. Andrea Flores, a senior fellow with the immigrant-advocacy group FWD.us, described a Latino electorate relieved that border crossings have slowed and that the disorder of the previous administration has passed, but uneasy about what's replaced it: on interior immigration sweeps, she said, "what ICE is doing, what Border Patrol is doing, they oppose that."
A Senate Race Still Too Close to Call
The contest most likely to be shaped by that shift is Texas' open U.S. Senate seat, where Democratic state Rep. James Talarico faces Republican Attorney General Ken Paxton. Ever since Paxton clinched the GOP nod in late May, a string of independent surveys has shown a persistent stalemate, with neither man cracking 50%. A Texas Public Opinion Research survey published by the Texas Tribune, fielded July 15–17, had Talarico ahead 45% to 40% — his largest edge of the general election so far. A Fox News poll found a similar trend, putting him up 51% to 48%. And the most recent entry, a Texas Southern University survey fielded July 27–30 and released Aug. 4, had Talarico ahead 47% to 45% — marking the third straight independent poll to show him narrowly in front. A June New York Times/Siena survey, by contrast, found the race tied at 47%.
Within that tightening race, Latino voters stand out as one of Talarico's strongest blocs — though the size of his lead depends heavily on which survey and which month. The Texas Southern poll put him ahead among Latino voters 57% to 38%; the July TPOR poll, fielded two weeks earlier, had him up by a wider 66% to 20%. An earlier bipartisan UnidosUS poll of Hispanic voters, fielded back in late April and May, found Talarico leading Paxton 51% to 24% among Texas Latinos specifically. All three surveys point the same direction, but the swings between them — from a 19-point lead to a 46-point one — are a reminder of how volatile polling of this subgroup can be, and how much can shift in just a few weeks.
Affordability, Not Ideology, Driving Movement
The UnidosUS survey found that just 15% of Latino voters in Texas describe themselves as living comfortably, while 62% ranked the cost of living as the top thing they want elected officials to address. Roughly one in five Texas Latinos who voted for Trump in 2024 now say they wouldn't do so again — driven mainly by frustration over inflation (cited by 46% of that group) and immigration enforcement in American cities (36%), rather than any single galvanizing issue.
Those cross-pressures were on display in Austin. Olivia Dominguez, who lost her job earlier this year, said she was frustrated with both the economy and immigration policy but stopped short of fully endorsing either party. "I would say maybe the Democrat might have an edge," she said. Gina Hinojosa, the Democratic nominee for governor, put the stakes more bluntly to the crowd, pointing back to Beto O'Rourke's 64% share of the Latino vote in his narrow 2018 loss to Ted Cruz: "When I get 64% of the Latino vote in 2026, I win."
Houston's Undercounted Bloc
What sets Harris County apart is turnout capacity, not sentiment. Local elections officials attribute the gap between the county's Latino population and its Latino electorate largely to age and citizenship status: less than half of Harris County Latinos are eligible to vote, compared with roughly three-quarters of white residents and about seven in ten Black residents, since a disproportionate share of Latinos are minors or noncitizens — including green-card holders and DACA recipients. That means the county's raw population advantage, larger than the Rio Grande Valley's combined electorate, doesn't automatically translate into votes — leaving both campaigns a persuasion-and-turnout opportunity that has drawn far less attention than the border region.
Immigration enforcement complicates that math further. The UnidosUS survey found 83% of Texas Latino voters support legalization for long-term undocumented residents in general — a figure that eases only slightly, to 80%, when the same proposal is specifically described as "amnesty." Separately, 45% say they or someone in their community fears being harassed or detained by immigration authorities, even among those who are citizens or legal residents, and roughly a third report that enforcement actions have already cost local employers workers.
With Election Day roughly three months out, neither party has locked down the loyalty of Texas' fastest-growing electorate. But the fight increasingly won't be decided in the Rio Grande Valley alone — it runs through Houston, too.
