Trader consensus prices a Republican victory at 89% for Oklahoma's open U.S. Senate seat, reflecting the state's strong Republican lean—evident in past elections with 20+ point GOP margins—and ratings from Cook Political Report and Sabato's Crystal Ball as Solid/Safe Republican. Sen. Markwayne Mullin's March 23 resignation to serve as DHS Secretary under President Trump prompted Gov. Kevin Stitt's appointment of Alan Armstrong, who pledged not to seek election, clearing the June 16 primary field. Rep. Kevin Hern leads the crowded Republican primary with $8.2 million cash-on-hand as of March 31, endorsements from Trump, Lankford, and Sens. Scott and Thune, plus early March Club for Growth polling showing him at 49% in matchups. Democrats' underfunded primary contenders pose negligible general election threat ahead of November 3.
