Has Colorado had a Democratic supermajority for two decades?

Tyler Hickman, The Colorado Sun
no

At no point in the last 20 years have Colorado Democrats held a supermajority in both chambers.

A supermajority is achieved when a party holds a two-thirds majority in each chamber, allowing it to override a governor’s veto and refer constitutional amendments to the ballot without bipartisan support, increasing its influence over state policy. 

Thirty-five senators and 65 representatives serve in the Colorado state legislature. A party would need 24 Senate seats and 44 House seats in any given year to gain that power. 

House Democrats held a supermajority in their chamber from 2022 until 2024, when Republicans flipped three seats. Both the House and Senate will be one vote shy of a two-thirds Democratic majority until the 2026 election.

Twenty-eight states have dual-chamber supermajorities in 2025, with Democrats in control in California, and Republicans in Utah, Wyoming and Idaho.
