Republican incumbent John Carter secured the GOP nomination in March 2026 with nearly 60 percent of the primary vote in Texas’s 31st congressional district, bolstered by an endorsement from President Trump. The district carries an R+11 Partisan Voter Index, anchored in Williamson County exurbs north of Austin and extending to military communities near Fort Hood, and all major forecasters rate the seat Solid or Safe Republican. Democrat Justin Early advanced from his primary but faces structural headwinds in a constituency that supported Republican presidential and Senate candidates by double-digit margins in 2024. Trader consensus at 93 percent for the Republican nominee reflects this combination of incumbency advantage, favorable partisan baseline, and absence of recent polling or campaign developments indicating a competitive contest. Late-cycle developments such as health concerns for the 84-year-old Carter or an unforeseen national political shift remain the primary variables that could narrow the margin before the November 3 general election.
