Democrats to Seek Colorado Legislative Supermajority in 2026

Live Poll

Would a legislative supermajority for one party be good for your state's policy direction?

Democrats are looking to establish a dual-chamber supermajority in the Colorado legislature during the 2026 election. Securing just one more seat in both the House and Senate would grant them the power to override gubernatorial vetoes.

Why it matters

A supermajority would significantly ease the passage of legislation regarding gun control and transgender rights while enabling the party to refer measures like the repeal of TABOR directly to the ballot.

Democrats have controlled the Colorado state legislature for eight years. Control of the Senate currently hinges on competitive election outcomes in District 30, District 3, and District 15.

The players

Colorado State Legislature

This is the lawmaking body of the U.S. state of Colorado consisting of the House of Representatives and the Senate.

The details

The potential supermajority represents a major shift in how the state government functions, as it would grant Democrats the ability to bypass executive veto power. Success depends on victory in three key districts: Douglas County’s District 30, Pueblo’s District 3, and Larimer County’s District 15.

The 2026 election will determine whether the party secures the required seats.
Democrats have held legislative control for the last eight years.
A potential first-time dual-chamber supermajority could arrive next year.

Political Context

Opponents often argue that a supermajority removes essential checks and balances provided by the gubernatorial veto, particularly concerning the Taxpayer's Bill of Rights. These groups emphasize the need for bipartisan cooperation to protect fiscal constraints and state constitutional limits.

If Democrats secure a supermajority, taxpayers may see rapid shifts in state regulations and the potential for new measures appearing on the ballot. Residents in District 30, District 3, and District 15 will see increased campaigning as these areas decide the chamber balance.

The takeaway

The 2026 election results will determine if Colorado experiences a significant change in its legislative governing power. Voters should monitor race results in their specific districts to understand how local representation influences state-wide veto power.
