Trump-backed candidate sparks runoff against popular prosecutor in key Oklahoma gubernatorial race

A Trump-backed candidate has sparked a runoff against a popular prosecutor in Oklahoma's key gubernatorial race. Former Oklahoma state Sen. Mike Mazzei and Attorney General Gentner Drummond advanced to the August 25 runoff after tying in the primary election. The runoff will determine the Republican nominee for governor, with the general election likely to be decided by November. The outcome is seen as a test of Trump's influence on the party in Oklahoma.
