Ballots for the November 2023 statewide election will start being mailed to Colorado voters today.

Here’s what you need to know to participate in the Nov. 7 contest. 

What’s on the statewide ballot?

There are two statewide measures on the November ballot — Proposition II and Proposition HH. The Colorado Sun is closely following both initiatives. 

Proposition II would let the state keep nearly $23.7 million in excess revenue from tobacco and nicotine taxes and use the money to bolster Colorado’s new universal preschool program. The measure would also let the state retain and spend future excess. 

If voters reject Proposition II, the tax revenue collected above what was projected will be returned to nicotine and tobacco wholesalers and distributors. Additionally, the nicotine and tobacco tax rates will be cut to prevent future excess revenue. 

For more on Proposition II, read our explainer.

Proposition HH is a highly complex 10-year property tax relief plan that would also grow the state budget, place new limits on local government spending and rework how taxpayer refunds are distributed.

All told, Proposition HH would limit the increase in Coloradans’ property taxes each year by hundreds of millions of dollars, if not more than $1 billion. But over time, Coloradans could get billions less in tax refunds as the state government redirects those dollars to schools and other local agencies.

What else is on the ballot? 

Many Coloradans will also vote in the election on local ballot initiatives, as well as school board and municipal races. Aurora and Boulder, for instance, are holding mayoral elections. In Denver, several school board seats are up for grabs.

Chalkbeat Colorado and The Sun held a virtual event about school board contests on Oct. 17. “From Quiet to Contentious: How did school board races become fueled by politics?” was moderated by Colorado Sun education reporter Erica Breunlin and Chalkbeat Colorado Bureau Chief Erica Meltzer.
