Four candidates are vying for the chance to be the Democratic nominee for governor of Colorado. Education has emerged as a key issue on the campaign trail, a point of debate and even a subject of negative campaign ads. Whoever wins the Democratic primary will face the victor of an equally competitive Republican primary.

They’ll be trying to hold on to an office that Democrats have controlled since 2007. Gov. John Hickenlooper cannot run again after serving two terms.

The primary is June 26. Ballots have already been mailed, and they must be received by your local county clerk no later than 7 p.m. on Election Day. For the first time, unaffiliated voters, who make up a third of Colorado’s electorate, can participate in the primary. Unaffiliated voters must pick ONE ballot. If you vote both a Democratic and a Republican ballot, neither will count.

Colorado’s next governor will have an important role to play in shaping education policy. To better understand their positions, we asked the candidates about their own educational experiences and choices, how they would close the achievement gap, whether Colorado should fund full-day kindergarten, and more.
