Trump's endorsement decisions in the 2026 midterm cycle have centered on primary contests, where his support has delivered a 97% win rate for backed candidates across congressional, state legislative, and executive races.

Broader patterns include earlier announcements than in prior cycles, more support for incumbents in safe seats, and targeted challenges to critics. With the general election on November 4, remaining primary runoffs and any late shifts in key battlegrounds could still influence final positioning before resolution.
