Jeff Pixley holds the leading position in the Oklahoma 4th Congressional District Democratic primary, scheduled for June 16, 2026, reflecting trader consensus on his profile as a retired Air Force colonel and fighter pilot. Mitchell Jacob, an Army veteran and attorney, trails as the only other candidate in the open-seat primary. A May 23 candidate forum in Grady County provided the most recent public opportunity for both to outline positions on district issues. With limited polling or endorsements reported in the preceding weeks, the implied probabilities align with available candidate backgrounds and low overall visibility for the race ahead of the general election against the Republican incumbent. No major late developments have shifted positioning since the filing period closed.
