President Donald Trump has issued more than 340 endorsements for 2026 Republican candidates, achieving a 96 percent primary success rate through early and repeated support for incumbents and challengers aligned with his America First priorities on immigration, taxes, energy, and the Second Amendment. Recent activity includes a September 1 slate of eight Florida House nominees and additional backing for candidates in New Hampshire and Ohio, continuing a pattern of Truth Social announcements that often clear primary fields or bolster general-election contenders. With the November 3 general election approaching, trader assessments of specific endorsement markets reflect Trump's history of selective intervention, preference for loyalists, and occasional dual or delayed picks in competitive races. Market resolution hinges on official announcements or credible reporting before Election Day, amid ongoing primary and general contests where his signals have historically moved outcomes.
