Gentner Drummond holds the strongest position in the Republican primary for Oklahoma governor, driven by his role as attorney general, consistent polling leads around 36 percent, and superior fundraising that has allowed sustained advertising. Recent surveys from early 2026 show him maintaining a double-digit advantage over a fragmented field where Mike Mazzei, Chip Keating, and Charles McCall remain statistically tied for second place, each drawing roughly 13 to 14 percent. This split among challengers raises the prospect of a June 16 runoff, which traders view as a key factor supporting Drummond’s implied probability near 43 percent. The primary’s open nature following term limits on the incumbent has intensified competition, yet no major shifts in endorsements or voter coalitions have emerged in recent weeks to alter the current ranking.
