Texas's 21st congressional district remains a solidly Republican seat following the departure of incumbent Chip Roy, who pursued a bid for state attorney general. The general election pits Republican nominee Mark Teixeira against Democrat Kristin Hook on November 3, 2026. The district's partisan lean, reflected in prior presidential and Senate results favoring Republicans by double digits, underpins the strong trader consensus favoring the Republican nominee. Recent primaries produced Teixeira as the nominee with endorsements from high-profile Republican figures, while limited Democratic polling shows the challenger trailing significantly. No major late shifts in the race have altered the structural advantage held by Republicans in this exurban Texas district.
