Elected Governor

Jared Polis
Democratic

The major party nominees were Democratic U.S. Representative Jared Polis and Republican State Treasurer Walker Stapleton. The general election took place on November 6, 2018, with Polis winning by 268,000 votes.[2][3] This was the first Colorado gubernatorial election in which both major party candidates received over one million votes.

Polis's victory marked the fourth straight election in which Colorado elected a Democratic governor and the first time in American electoral history that an openly gay politician was elected governor of a state.

Democratic primary

edit

With Hickenlooper ineligible to run for a third term in office, multiple Democratic politicians vied for the party's nomination for governor. Prior to his resignation in 2015, former lieutenant governor Joseph Garcia was seen as a probable candidate for governor in 2018.[4]
