Primary elections held on June 16, 2026, across Georgia and Oklahoma are serving as a significant test of Donald Trump's endorsement power within the Republican party. In Georgia, Trump-backed Mike Collins has won the Republican Senate primary runoff, a victory that is expected to provide him with a substantial financial boost of $1 million for his upcoming campaign. This win solidifies his position in a key contest. However, not all Trump-endorsed candidates were successful. Lt. Governor Burt Jones, who had received endorsements from both President Donald Trump and Governor Brian Kemp, lost the Georgia Republican gubernatorial primary runoff to businessman Rick Jackson. Jackson will now face Democrat Keisha Lance Bottoms in the general election.
In Oklahoma, the Republican primary for the 1st Congressional District is heading to a runoff. Jackson Lahmeyer, founder of Pastors for Trump, and state Representative Mark Tedford are projected to advance, as neither candidate secured over 50% of the vote. Voters in Oklahoma are also participating in primaries for other races, including the Oklahoma gubernatorial race and the open House seat succeeding Rep. Kevin Hern, who is running for Senate. Polls in Oklahoma were set to close at 8 p.m. EDT.
Beyond Georgia and Oklahoma, Washington D.C. voters are participating in their Democratic primary to elect a new mayor. City Councilmember Janeese Lewis George is reportedly leading in early polling.
