Trump’s endorsements have shaped Republican primaries throughout the 2026 cycle, delivering a roughly 96-98 percent success rate across hundreds of congressional and statewide contests. Recent activity centers on general-election support, including a September 1-2 batch of eight Florida House candidates in open and competitive districts, following primary upsets and alignments with state-level figures. Strategy favors early backing of incumbents while using late or dual endorsements to manage contested races, as seen in prior gubernatorial runoffs. Remaining September primaries in states such as New Hampshire, plus ongoing Senate and gubernatorial contests, provide near-term catalysts that could shift trader focus on specific candidates or timing.
