Gentner Drummond holds the lead in Oklahoma’s June 16 Republican gubernatorial primary as the sitting attorney general, backed by superior fundraising, public-safety union endorsements, and statewide name recognition that has kept him ahead in most recent polls. Recent attack ads from MAGA-aligned groups have highlighted his past campaign donations and positions on certain social issues, narrowing his advantage and lifting Chip Keating and Mike Mazzei as fiscal-conservative alternatives. House Speaker Charles McCall remains competitive through targeted polling and rural support, while the rest of the field trails far behind in a fragmented contest. Traders appear to price in Drummond’s structural edges alongside the risk that negative advertising could consolidate opposition votes before the primary.
