Republican control of congressional districts in South Texas faces significant challenges ahead of the midterm elections, according to recent polling data and political analysis. After redrawing the state’s congressional map last year under instructions from President Donald Trump, the party initially anticipated sustained support from Latino voters who helped secure Trump’s 2024 victory. However, new surveys indicate a shift in voter sentiment, driven by economic pressures and changes in immigration enforcement policy.
What the Right Is Saying
Republicans maintain that their redistricting strategy was based on the strong performance of President Trump in the region during the 2024 presidential election, where he won the newly drawn 15th district by 18 percentage points. The party leadership, including President Trump, had instructed the Texas Legislature to redraw the map believing that the coalition of Latino voters concerned about the border crisis would remain aligned with the GOP. Incumbent Rep. Monica De La Cruz won her 2024 race by 14 points, a margin Republicans viewed as a durable base for future contests.
Conservative analysts argue that the current polling volatility reflects short-term dissatisfaction rather than a fundamental rejection of Republican principles. They point to the continued strength of Trump’s brand in rural areas and among voters who prioritize border security above economic concerns. However, the reclassification of key races from 'lean Republican' to 'toss-up' by non-partisan analysts has raised internal concerns about the durability of the 2024 coalition.
What the Left Is Saying
Democratic strategists and political analysts argue that the Republican approach to South Texas has alienated the very voters who swung the region in 2024. Jon Taylor, a political science professor at the University of Texas at San Antonio, noted that while border concerns initially drove Latino voters toward Trump, the subsequent implementation of heavy-handed immigration enforcement and tariffs on Mexico has created a cumulative negative effect on the local economy and community relations.
Taylor stated that Democrats could potentially win all South Texas districts in the upcoming midterm elections. He emphasized that Latino voters in Texas have become a swing vote bloc, suggesting that the shift toward Democrats is a reaction to current policies rather than a permanent ideological realignment. The Democratic campaign in Texas’ 15th congressional district, led by Tejano singer Bobby Pulido against incumbent Republican Rep. Monica De La Cruz, is capitalizing on these economic and social concerns to close the gap.
What the Numbers Show
According to a September poll published by Cook Political Report, Hispanic voters in three congressional districts in South Texas now favor Democrats, with a 14-point lead. This represents a significant reversal from the 2024 election cycle. Cook Political Report moved the race in Texas’ 15th congressional district from lean Republican to a toss-up in late September. Similarly, the race in Texas’ 35th congressional district, where Air Force veteran Carlos De La Cruz is running against Democrat Johnny Garcia, was also reclassified from leaning Republican to a toss-up.
A recent Washington Post-Schar School poll indicates that President Trump’s approval rating has declined in the 35th district, an area he won by 10 percentage points in 2024. The poll found that 24% of Trump supporters in the district now disapprove of his job performance. Furthermore, roughly half of all voters in the district reported feeling financially worse off since Trump’s return to the White House, highlighting the economic dimension of the voter shift.
The Bottom Line
The shift in Latino voting patterns in South Texas underscores the volatility of swing districts and the impact of economic policy on electoral outcomes. If Democrats succeed in winning these seats on November 3, it will signal that the 2024 realignment was temporary and contingent on specific border-related issues. Political analysts advise both parties to treat Latino voters in Texas as a permanent swing bloc rather than a reliable constituency for either side. The outcome of these races will likely determine the balance of power in the House and influence future redistricting efforts in the state.
