On Tuesday, August 26, 2026, former President Donald Trump achieved two significant victories in GOP primary runoff elections across the United States. Sen. Darline Graham of South Carolina and former state Sen. Mike Mazzei of Oklahoma both clinched their party’s nominations in their respective races.

Trump’s super PAC, MAGA Inc., played a notable role in these outcomes, contributing over $800,000 to support Graham’s campaign effort. These races were widely viewed as a test of Trump’s continuing influence within the Republican Party.

The wins underscore Trump’s ability to mobilize resources and sway GOP primary contests, reinforcing his role as a key power broker ahead of upcoming elections.
