Texas Senate 2026

2020 result: Cornyn 53.5% vs. Hegar 43.9% — a 9.6-point margin. Trump won Texas by 5.8 pts that year, meaning Cornyn outperformed Trump by ~4 pts. However, early 2026 polling shows Talarico (D) ahead of Cornyn in registered voter surveys — an unusual situation driven by Cornyn’s weaknesses and a strong Democratic environment.

Cornyn’s Weaknesses and the Paxton Variable

John Cornyn enters 2026 in a structurally weakened position for a senior Republican senator in Texas. In November 2024, he ran for Senate Majority Leader to replace the retiring Mitch McConnell and lost 29–24 to South Dakota’s John Thune — a stinging defeat that left him without any Senate leadership position after two decades as a fixture of Republican Senate management. That visibility loss matters in a primary environment where conservative voters reward power and proximity to Trump, and Cornyn’s vote record and dealmaking history give MAGA challengers ample ammunition.

Ken Paxton’s entry into the race has complicated what should have been a straightforward re-election. Paxton, who resigned as Texas AG in January 2025 specifically to run for Senate, carries two significant legal liabilities: a federal securities fraud indictment from 2015 that remains unresolved, and the 2023 Texas House impeachment (he was acquitted by the Texas Senate in proceedings widely seen as politically motivated). Paxton is running on a hardline MAGA platform, attacking Cornyn as too willing to work with Democrats on legislation like the bipartisan infrastructure bill. In the runoff, Paxton leads narrowly — Paxton 48%, Cornyn 45% per May 2026 polling — making the Republican primary the most consequential near-term event in this race.

Democrat James Talarico has emerged as an unusually strong general election candidate for Texas. A former schoolteacher turned state representative from the Austin suburbs (Williamson County), Talarico won the Democratic primary and immediately attracted attention with polling showing him ahead of both Cornyn and Paxton in registered voter surveys. A University of Texas/Texas Politics Project poll (April 2026) showed Talarico 44%, Cornyn 41%; and Talarico 42%, Paxton 34%. These leads are in registered voter models — likely voter models, which skew more Republican, would probably show a narrower picture. All major forecasters still rate the race Likely Republican, noting that Trump’s 14.2-point 2024 Texas margin creates a structural floor for any Republican nominee.

Note: This is Texas’s Class 2 Senate seat (Cornyn’s seat). The other Texas seat is Class 1, held by Ted Cruz (won re-election 2024, not up until 2030). Cornyn’s Class 2 seat has been held by Republicans continuously since John Tower won it in 1961 — Phil Gramm held it 1985–2002 before Cornyn. The Class 1 seat (Ted Cruz) was the one KBH won in 1993.

The 2026 midterm elections are taking place in an environment shaped by significant economic uncertainty. Trump's Liberation Day tariffs triggered a consumer confidence collapse and PCE inflation surged to 4.5% in Q1 2026. The Trump approval rating stands at 38.1% approve / 59.2% disapprove — among the lowest for any first-year president since modern polling began. The Generic Ballot shows Democrats with a consistent +6.0 advantage, a historically predictive indicator of significant House seat gains.

In the Senate, 33 Class 2 seats are up in 2026. Republicans must defend seats in Georgia, Iowa, North Carolina, Alaska, and Texas, while Democrats defend Nevada, New Hampshire, Michigan, Minnesota, and Virginia. Key battleground races that will determine Senate control include Georgia (Jon Ossoff, D), Iowa (open seat, Ernst retires), Nevada (Jacky Rosen, D), and Alaska (Lisa Murkowski, R).

Issue-level polling context: The top issues driving 2026 are the economy and tariffs, healthcare, immigration, and Social Security. See the Battleground Tracker for the latest state-level polling and the Trump Policy Tracker for executive action context.
