Incumbent Ronny Jackson secured the Republican nomination in the March 2026 primary with nearly 90 percent of the vote against a single challenger, while Mark Nair advanced unopposed in the Democratic primary. Texas's 13th District, encompassing much of the Panhandle and parts of the Texoma region, has delivered consistent Republican margins exceeding 40 points in recent cycles, including strong support for presidential candidates. Jackson's substantial fundraising lead and endorsements from party leaders reinforce his position ahead of the November general election. Forecasters rate the seat as safely Republican. A late scandal, health event, or unusually strong national Democratic wave would be required to meaningfully narrow the gap.
