Colin Allred secured the Democratic nomination for Texas's 33rd congressional district after defeating incumbent Julie Johnson in the May 2026 runoff, while Patrick Gillespie advanced as the Republican nominee. The newly configured Dallas-area seat carries a strong Democratic lean following redistricting, with nonpartisan ratings classifying it as Solid Democratic. Allred's prior House service and Senate campaign experience, combined with a substantial fundraising edge, underpin trader expectations for a Democratic victory in the November 3 general election. The spread across margin brackets reflects limited general-election polling data and the typical variability in safe-seat outcomes, where turnout patterns and local mobilization could influence the final margin within the 40-55% range most heavily weighted by the market. Early voting begins October 19.
