What this office is
Each state elects two U.S. senators. A senator’s term is six years. Class 2 seats are on the regular 2026 cycle. The Senate writes and votes on federal legislation, confirms many presidential nominees, and tries impeachments. The winner of a November general election takes office only after the state’s official canvass and the new Congress is seated.
Why it matters in 2026
Cook moved Texas from Lean Republican to Toss Up on August 20, 2026, citing public and private polling in a state Trump won by a double-digit margin in 2024. Reuters and CBS have treated the race as a surprise battleground. Official canvass remains a Texas function.
The Class 2 seat is open after Sen. John Cornyn lost the 2026 Republican primary to Attorney General Ken Paxton.
Primary outcomes are historical facts reported by news outlets and Ballotpedia. November names must still be confirmed on the official Texas ballot.
