Jessica Steinmann's decisive victory in the March 3 Republican primary solidified her as the GOP nominee for the open TX-08 House seat, following Rep. Michael McCaul's September 2025 retirement announcement, driving trader consensus to price a Republican win at 89.5%. The district's strong Republican lean, rated Solid Republican by Cook Political Report, stems from consistent double-digit GOP margins in prior cycles amid Montgomery and Walker County strongholds. Democrat Laura Jones advanced unopposed in her primary but faces fundraising disadvantages, including recent AI super PAC infusions benefiting Steinmann. Absent competitive polling and with the November 3 general election distant, markets reflect low upset risk despite national midterm dynamics.
