Latest election results: Colorado Democrats lose out on a state Senate supermajority, 2 seats determine the state House

COLORADO, USA — The balance of power in the Colorado legislature could look a little different after the 2024 election, but we won’t know how different until final vote tallies are made in a handful of races. So, what does that mean for Democrats and Republicans? 

It means we’re still waiting to see if Colorado Democrats will maintain their supermajority in the state House after they narrowly lost out on a supermajority in the Senate.

Colorado Democrats needed all four remaining Senate contests to swing their way to gain a supermajority in the state Senate. At 11:49 a.m. on Thursday, the Associated Press called state Senate District 15 for Republican Marc Catlin over his Democratic opponent, Cole Buerger.  Catlin bested Buerger by about 4%, or 3,500 votes.

The last state Senate race left to be called is District 21, which covers parts of Adams and Arapahoe counties. With 97% of the votes counted, per the AP, Democratic incumbent Dafna Michaelson Jenet leads Republican Frederick Alfred by about 1,400 votes. If Jenet wins, Democrats maintain their prior hold on the chamber.

Prior to the election, Democrats held a supermajority in the state House, meaning they made up two-thirds or more of the majority. In the Senate, Democrats were one seat away from a supermajority. Why is that important? Most votes in the legislature require at least a two-thirds majority to pass.

There were 83 legislative seats up for election this year —18 in the Senate and 65 in the House. 

In the Senate, 12 of those seats were previously held by Democrats and six by Republicans. Currently, nine have been won by Democrats, five by Republicans.

In the House, 46 seats were held by Democrats and 19 by Republicans. Currently, 43 have been won by Democrats and 20 by Republicans.

Two state House races are still too close to call — Democrats need to win at least one of those seats hold their supermajority in the chamber. 

Those House races are in districts 16 and 19. District 16 is historically a toss-up — Republican Rebecca Keltie leads Democratic incumbent Steph Vigil by just 11 votes as of AP’s last update on Saturday.

District 19 was entirely redistricted in 2023, and active voter registration numbers indicated the race would be close. Republican Dan Woog leads Democrat Jillaire McMillan by 207 votes as of AP’s last update on Saturday.

A supermajority in both chambers would have given Colorado progressives the power to push a more aggressive agenda through the legislature on things like social and environmental issues, and siding with labor unions over business interests.

Even without two supermajorities, large numbers would bolster Democratic majorities on legislative committees that determine which bills make it to a floor vote.

Republicans, on the other hand, hoped to flip enough seats in both chambers to restore a party balance to the legislature, giving them more influence over the state’s fiscal decisions.

9NEWS went through House and Senate race to anticipate the state’s most competitive districts based on party affiliation of active registered voters, results and margins of previous elections, as well as recent redistricting. 

We also consulted political strategists and party leadership working on both sides of the aisle, Republican and Democrat, to see what races the parties will be watching come election night.

From our research, we made a list of races to watch, which included state Senate districts 5, 12 and 16.
