The Latino Voter Shift and Its Limits
The Texas border belt's shift toward Republicans between 2016 and 2024 is one of the most significant demographic realignments in modern American electoral history. Counties like Starr (97% Hispanic) and Zapata (90% Hispanic) flipped from margins of D+60 in 2016 to competitive or Republican territory by 2022. Monica De La Cruz's 2022 win in TX-15 was the capstone: a Hispanic Republican woman winning a majority-Hispanic Rio Grande Valley district. The drivers were complex — cultural traditionalism, frustration with border disorder under Democratic governance, economic conservatism among working-class voters who rejected the cultural messaging of national Democratic politics, and effective Spanish-language Republican outreach. Trump's 2024 performance in the Valley cemented the gains.
The limits of this shift are now being tested. Mass deportation raids that separated community members from families have generated real anxiety along the border. Economic disruption from the tariff regime — particularly the 25% tariffs on Mexican goods, which are felt immediately in border-adjacent communities deeply integrated with the Mexican economy — creates direct pocketbook concerns. The narrative that Republicans are good for the border economy is under pressure for the first time since the shift began.
TX-28: Cuellar's Legal Jeopardy
Henry Cuellar, the last anti-abortion Democrat in the House, represents TX-28 and faces legal problems that have made his seat the most precarious Democratic-held competitive seat in Texas. Cuellar and his wife were indicted in May 2024 on federal bribery charges related to alleged payments from a Mexican bank and the Mexican government. The case is proceeding toward trial, and Democrats face the prospect of running either Cuellar (legally compromised) or a replacement candidate (lacking name recognition) in a Laredo-area district that has drifted rightward. The DCCC has spent considerable resources recruiting a fallback Democratic candidate in the event Cuellar steps aside or is convicted. Rated Toss-up.
TX-34: Gonzalez Holds the Valley Anchor
Vicente Gonzalez holds TX-34, which covers the Brownsville-McAllen metro area and represents the most Democratic-leaning of the four competitive border districts. Gonzalez moved from the adjacent TX-15 after redistricting, running in the safer D+5 seat while ceding TX-15 to De La Cruz. His district includes significant international trade infrastructure, maquiladora supply chains, and healthcare sector employment, all of which have been disrupted by the tariff regime. Gonzalez is a skilled incumbent who has won multiple close races and is rated Lean D. Republicans see TX-34 as a stretch target; the national environment would need to tilt significantly in their favor to produce a flip. However, TX-28 and TX-34 together represent the Democrats' most exposed flank in the South.
Frequently Asked Questions
Which Texas House races are competitive in 2026?
TX-15 (De La Cruz R, Lean R), TX-23 (Gonzales R, Lean R), TX-28 (Cuellar D, Toss-up due to indictment), and TX-34 (V. Gonzalez D, Lean D). All four are border-adjacent with majority-Hispanic populations.
Why did the Texas border shift Republican?
Cultural conservatism, frustration with border disorder, working-class economic conservatism, and effective Spanish-language Republican outreach drove the shift between 2016 and 2024. Counties that were D+60 in 2016 became competitive by 2022. The trend may face headwinds in 2026 from immigration raids and tariff disruption to the border economy.
What is the status of Henry Cuellar in TX-28?
Cuellar was indicted in May 2024 on federal bribery charges. The case is proceeding toward trial. His legal jeopardy makes TX-28 a Toss-up; the DCCC is preparing for both scenarios — Cuellar running or a replacement candidate. It is Democrats' most exposed competitive seat in Texas.
