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, AP 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 Democrat-favoring partisan balance in the Colorado Legislature will look similar to the previous two years, based on early results from Tuesday’s election, though a couple of races remain too close to call as of publication time.
