How does Texas’s Senate delegation currently break down by party and when are their next elections?

1. Two senators, both Republican — the current delegation

Texas has two members in the U.S. Senate and both are Republicans: John Cornyn and Ted Cruz are identified as the state’s senators in current listings ^{[1] [2]}. Multiple assembled sources and trackers reiterate that both U.S. Senate seats from Texas are held by Republicans and that Democrats have not held a Texas Senate seat since the early 1990s in the cited reporting ^{[4] [2]}.

2. Which seat is up when — the 2026 contest and the other class

Reporting and election trackers show a U.S. Senate election in Texas scheduled for November 3, 2026, with party primaries on March 3, 2026 and a May 26, 2026 primary runoff date; Ballotpedia’s page on the 2026 Texas Senate race lists candidates and the calendar for that cycle ^[3]. Ballotpedia’s overview ties those dates to the Class I term that runs Jan. 3, 2025–Jan. 3, 2031, indicating the 2026 general election will select the senator for the seat contested in that cycle ^{[2] [3]}. Available sources do not provide an explicit single-line mapping of which incumbent occupies which class in the snippets provided, but they do identify that an election is set for 2026 and list candidates filing for that race ^{[3] [2]}.

3. Who’s running and intra-party dynamics reported

Ballotpedia and related reporting list multiple Republican candidates in the 2026 cycle, including high-profile filings and intra-party competition; John Cornyn, Wesley Hunt, Ken Paxton and others were named as participants in the Republican primary for the 2026 U.S. Senate contest in Texas ^{[3] [5]}. Ballotpedia news frames the GOP primary in Texas as crowded and sometimes contentious, noting Cornyn has faced criticism from conservative elements for prior bipartisan actions ^[4]. These sources show the Republican primary is a focal point for the seat up in 2026 ^{[3] [4]}.

4. Partisan balance of the wider Texas congressional delegation

Beyond the Senate, trackers note Texas’ broader congressional delegation is dominated by Republicans: multiple sources list the U.S. House count from Texas as heavily Republican (for example, Ballotpedia News reports 25 Republicans and 12 Democrats in the House delegation as of late 2025) ^{[4] [6]}. Those tallies contextualize why both Senate seats are Republican-held and why the 2026 Senate race is receiving attention from both parties ^{[4] [6]}.

5. Where reporting is explicit — and where it’s not

The provided sources explicitly state that both Texas U.S. senators are Republicans and that a Senate election will be held in 2026 with primaries March 3, 2026 and general election November 3, 2026 ^{[1] [2] [3]}. The sources name candidates running in the 2026 cycle and describe intra-party dynamics ^{[4] [3]}. Available sources do not include a concise, single snippet in these results that labels which senator occupies Class I versus Class II in the exact quoted lines here; they do, however, describe the Class I term span and link it to the 2026 cycle ^{[2] [3]}.

6. What this means politically — why the 2026 seat matters

Election trackers characterize the 2026 Texas Senate race as strategically significant even if not initially a top Democratic pickup target; the crowded Republican primary and the presence of high-profile intraparty challengers suggest the real contest may play out within the GOP as much as between parties ^{[3] [4]}. The broader Republican advantage in Texas’s congressional delegation underscores why national forecasters are watching candidate quality and turnout rather than just raw partisan ID ^{[4] [6]}.

Limitations: this summary relies solely on the provided sources; detailed, up-to-the-minute lists of which senator is in which class or the full list of declared candidates may be available elsewhere but are not contained in the supplied snippets ^{[2] [3]}.
