Incumbent Republican Sen. Markwayne Mullin resigned in late March 2026 to become DHS Secretary under President Trump, prompting Gov. Kevin Stitt to appoint Alan Armstrong as interim replacement—who, per state law, cannot run for the full term—creating an open race rated Solid Republican by Cook Political Report and others. U.S. Rep. Kevin Hern leads the crowded GOP primary field with 52% in a March poll, bolstered by Trump and Sen. James Lankford endorsements, while Democrats field lesser-known challengers like attorney R.O. Joe Cassity amid Oklahoma's R+20 partisan lean and unbroken GOP Senate streak since 1994. Trader consensus at 93.5% Republican reflects this dominance, though a post-primary GOP scandal, Hern primary upset, or national Democratic surge could narrow odds ahead of the June 16 primaries.
