Incumbent Lt. Gov. and Republican Spencer Cox defeated candidate Chris Peterson 64% to 30% in Utah’s gubernatorial race.

Cox, the top finisher among state Republican convention delegates, beat three GOP candidates in the June 30 party primary.

Those are former Gov. Jon Huntsman Jr., former Utah House Speaker Greg Hughes, and former Utah Chairman Thomas Wright.

Peterson, a University of Utah law professor who worked on consumer issues in the Obama administration, won the Democratic nomination outright at his party’s state convention and did not face a primary in his first run for public office.

Cox will succeed Republican Gov. Gary Herbert.

Herbert chose not to run for reelection after more than a decade in office and endorsed Cox in the hotly contested GOP gubernatorial primary.
