The solidly Republican character of Texas’s 21st congressional district, with its Cook PVI of R+10 and consistent GOP victories since 1978, underpins trader consensus around Mark Teixeira. The open seat created by Chip Roy’s retirement after an unsuccessful attorney general bid further favors the Republican nominee, who secured 60.9 percent in the March primary against a crowded field. Teixeira’s substantial fundraising edge, including significant self-funding, name recognition from his MLB career, and endorsements from state and national Republican figures, reinforce the position ahead of the November 3 general election. Kristin Hook’s Democratic primary win and lower-profile campaign have produced limited movement in market pricing. A late surge in Democratic turnout or an unforeseen development affecting Teixeira could narrow the margin, though current fundamentals show no such shift.
