Mark Teixeira holds a commanding 92% implied probability in the TX-21 general election on November 3, 2026, driven by the district’s consistent Republican lean of roughly R+10, his decisive 60.9% primary victory, and high-profile endorsements including from President Trump. The former MLB player benefits from substantial name recognition, a large fundraising edge exceeding $3.6 million, and alignment with conservative priorities on border security, taxes, and spending. Kristin Hook, the Democratic nominee who won her primary with 60%, previously lost the seat by a wide margin in 2024. Recent campaign activity has centered on Teixeira’s outreach on economic issues and law enforcement support, with no major late developments reported that have shifted the race. Scenarios that could still alter outcomes include unexpected turnout surges, significant scandals, or health events, though the seat’s structural advantages favor the Republican nominee.
