Healthcare Takes Center Stage in South Texas House Battles Amid Rising Costs

Healthcare costs and access are emerging as defining issues in South Texas’ closely contested U.S. House races, where Democratic candidates are leveraging Republican-backed policy changes to challenge GOP incumbents in districts that will help determine control of the narrowly divided chamber.

Democratic challengers in five competitive House races across the Rio Grande Valley and surrounding areas are highlighting healthcare affordability in campaign messaging, a strategy driven by recent federal policy shifts that have increased financial burdens on residents. The expiration of enhanced Affordable Care Act (ACA) premium subsidies in January has particularly affected the region, where nearly one in five residents relies on ACA marketplace coverage. Without these subsidies, many face significantly higher premiums, exacerbating existing disparities in a region where uninsured rates exceed the national average by more than double.

The healthcare debate is unfolding against a backdrop of chronic health challenges in South Texas. According to a decade-long study, more than 40% of adults in the region suffer from diabetes, while 25% are affected by obesity—conditions that require consistent, long-term medical care. However, many residents, particularly those without insurance or with limited financial resources, delay or forgo necessary treatment. Rashmi Chandran, a clinician and hospital administrator in the Valley, noted that patients often limit care to a single annual visit or only seek treatment when symptoms become severe, skipping follow-ups and prescription refills.

Democrats are framing the GOP’s 2025 healthcare-related legislation, including the One Big Beautiful Bill Act, as a direct threat to affordable healthcare. The law, passed by House Republicans in July 2025, includes an estimated $911 billion in Medicaid spending cuts over the next decade. Democratic candidates are tying these cuts to rising costs, arguing that Republican policies prioritize tax reductions for high earners while shifting financial burdens onto working families. Their campaign ads emphasize preserving ACA subsidies, protecting Medicaid, and lowering prescription drug costs—issues that resonate in a region where economic stress and healthcare affordability are top concerns.

Recent polling underscores the potency of these arguments. A June 2025 survey by the Texas Politics Project found that 52% of Texas voters disapproved of President Donald Trump’s handling of healthcare, compared to 31% who approved. Across South Texas’ competitive districts, healthcare consistently ranks among voters’ top priorities, trailing only cost of living and broader economic concerns. In response, Republican candidates have focused their messaging on border security and tax cuts, while largely avoiding direct engagement on healthcare policy.

The financial stakes are evident in the volume of campaign spending. According to AdImpact, candidates and outside groups in four key South Texas races have spent over $3 million on healthcare-related ads, more than double the amount allocated to inflation or job concerns. Democrats have outspent Republicans on these ads by a significant margin, using them to link GOP-backed legislation to personal financial strain.

The strategic emphasis on healthcare appears to be yielding results. Earlier this month, the nonpartisan election forecaster Sabato’s Crystal Ball shifted the race in Texas’ 15th Congressional District—where Democratic candidate Bobby Pulido is challenging incumbent Monica De La Cruz—from “lean Republican” to “toss-up.” Pulido, a Tejano musician and first-time candidate, has made healthcare central to his campaign, arguing that residents should control their own medical decisions rather than defer to politicians. De La Cruz, who voted for the GOP’s healthcare bill, has countered with ads positioning herself as a fighter for affordable healthcare, though her messaging has not matched the intensity of her opponent’s attacks.

Elsewhere in South Texas, Democratic incumbents Vicente Gonzalez and Henry Cuellar hold narrow polling leads over their Republican challengers in districts that were redrawn last year to favor GOP candidates. Gonzalez leads by 3 points in the 34th District, while Cuellar holds an 11-point advantage in the 28th District. Meanwhile, in the open 23rd District, Democrat Katy Padilla Stout is contesting the seat left vacant by former Republican Congressman Tony Gonzales, with national Democrats recently adding the race to their target list.

The shift in electoral dynamics reflects broader dissatisfaction with healthcare costs and growing skepticism toward Republican policy priorities in a region where economic pressures weigh heavily on voters. As Election Day approaches, the outcome in South Texas may hinge on which party succeeds in convincing residents that their vision for healthcare aligns with the needs of families across the Rio Grande Valley.
