The open TX-21 House seat, vacated by incumbent Chip Roy for his Texas attorney general bid, favors Republicans at 84.5% implied probability following former MLB star Mark Teixeira's dominant 63% win in the March 3 Republican primary over a crowded field. The district's R+11 Cook Partisan Voter Index, where Donald Trump carried 59% in 2024, underscores its safe Republican status, with no general election polls indicating competitiveness against Democratic nominee Kristin Hook, the 2024 loser here. Cook Political Report rates it Solid Republican, reflecting trader consensus on GOP structural advantages absent major shifts before the November 3 general election.
