Rep. James Lankford (R-Okla.) won the Oklahoma Senate primary outright on Tuesday, making him the odds-on favorite to replace retiring Sen.

Lankford topped the critical 50 percent mark in the seven-way primary, avoiding an August runoff, where Shannon could have marshaled conservatives in an election likely to have lower turnout.
A second-term congressman and junior member of House leadership, Lankford benefitted from Mississippi's surprise Senate runoff, which drew money and attention from national conservatives that could have otherwise been targeted at him.

Shannon, who is also of Native American heritage, would have been the Senate's second African-American Republican in the current session.
But instead, Mississippi pushed the race out of the national spotlight, and the cash-strapped Shannon struggled to maintain his momentum without more outside money. Lankford also got a boost from Coburn, who stopped short of endorsing him but attacked the outside groups running ads against him and complimented the congressman’s integrity in remarks Lankford used heavily in his final ad push.
Former Oklahoma state Sen. Steve Russell (R) and state Corporation Commissioner Patrice Douglas (R) advanced to a runoff for Lankford's House seat.
