Texas 15th District Polls Show Democratic Lead Despite Redrawn Map

Voters in the Rio Grande Valley of Texas are moving away from the Republican Party ahead of the November 3 midterm election. In Texas’s 15th congressional district, polling now shows a five to six point lead for the Democratic candidate. This shift occurs despite state lawmakers redrawing the district in 2025 to give Republicans an 18 point advantage on paper.

The 15th district includes the Rio Grande Valley, a region that delivered Donald Trump a record 55 percent of Hispanic votes in 2024. That support helped secure a Republican majority in the state legislature, which used its power to redraw congressional maps earlier than usual. Lawmakers believed the 2024 voting pattern would persist. Current surveys taken since late summer contradict that assumption.

Local economic conditions are driving the change. Mario Guerrero, a Mexican American businessman who leads the South Texas Builders Association, voted for Trump three times but plans to support the Democrat in November. Guerrero noted that his construction crew of 35 daily workers has shrunk to four or six. He stated that voters were not told how far the administration would go with its enforcement actions.

Immigration enforcement remains a central issue in the community. At the La Lomita Catholic Chapel near the Rio Grande, Father Roy Snipes addressed a congregation of about 30 people on the actions of Immigration and Customs Enforcement. Snipes, who has served the area for nearly 50 years, said there is no good excuse to detain neighbors. Government data obtained by the Deportation Data Project indicates Texas accounted for one third of all ICE arrests nationwide in July 2026.

Bobby Pulido, the Democratic candidate in the 15th district, has campaigned on local economic concerns rather than national party branding. Pulido, a two time Latin Grammy winner, told voters in the valley that the local economy is distinct from major coastal cities. Republican Mayor Javier Villalobos of McAllen acknowledged the race will be difficult. He said most residents accept the deportation of criminals but object to the removal of law abiding workers.

Republican strategists admit the national political environment poses a challenge. Tano Tijerina, the Republican candidate in the neighboring 28th district, said the headwinds are real. Student volunteer Alexis Uscanga described the midterm election as a game of turnout. If current polling trends hold, a swing back to Democrats in this district could influence other races in the state.

The potential for a Democratic gain in Texas has broader implications for the 2026 elections. A shift in this district could be enough to put a United States Senate seat in play. Democrats have not won a Texas Senate seat in more than 30 years.
