- Will the Republican Party win the TX-31 House seat?95¢95%
- Will the Democratic Party win the TX-31 House seat?4¢4%
The TX-31 district's R+11 Cook Partisan Voter Index and John Carter's incumbency since 2003 anchor trader consensus around his 94.5% implied probability. Carter secured the Republican nomination in the March 2026 primary with nearly 60% of the vote against multiple challengers, while recent redistricting and consistent Republican performance in presidential and statewide races have reinforced the seat's structural advantage. Carter's $1.5 million fundraising total through mid-October far exceeds Justin Early's totals, and multiple forecasters rate the race Safe or Solid Republican with projected margins exceeding 10 points. Early, who won his primary, emphasizes affordability and veterans' issues but faces the district's established partisan baseline. Late-breaking events such as a major scandal or health development could still alter outcomes before the November 3 election.
