President Donald Trump has issued more than 280 endorsements in the 2026 Republican primary cycle, concentrating on House races while selectively entering Senate contests and state-level primaries. His recent focus includes over 130 Texas Republican primary endorsements ahead of May runoffs, with no choice yet announced in the high-profile Senate matchup between incumbent John Cornyn and challenger Ken Paxton. Trump stated in early May that he would decide soon and urged the non-endorsed candidate to exit the race. In Louisiana, his backing of Rep. Julia Letlow against Sen. Bill Cassidy has shaped that Senate primary dynamics. These moves reflect Trump's continued influence over GOP candidate selection ahead of November general elections, with traders monitoring statements on Truth Social and campaign events for signals on remaining open races.
