Texas 37th District

OPEN SEATSafe DREDISTRICTEDWhy the lines changedTexas redrew its congressional map in the middle of the decade through HB 4, which Gov. Greg Abbott signed on Aug. 29, 2025. A federal court blocked the map, but the U.S. Supreme Court put that ruling on hold in December 2025 and reversed it in April 2026, so the new lines are in place for 2026. It becomes somewhat more Democratic, going from Harris +49.3 to Harris +56.6 in the 2024 presidential vote.Source ↗

Lloyd Doggett (D) has held this seat since 2023 and is not running; the district was redrawn in September 2025.

FTP Race Signal

FTP Race SignalA composite of market, polling and money. The prediction-market price anchors it; a polling average moves it: the last 30 days, or the three most recent pollsters when fewer polled. Polls paid for by a candidate, party or allied group move 2 points toward the other side and count half. When the three most recent independent pollsters each have the race within three points, it is a Toss-up unless the market is already decisive. Fundraising counts only at a five-to-one gap. Past results are context, not inputs. A rating changes only when the evidence clears the line.

This district was redrawn in September 2025; the 2024 result on the previous lines does not describe it. The market prices the new seat at 99.6¢ Democratic.
