Interestingly, it seems that Colorado Republicans had Trump removed from the ballot.

PER CURIAM. 1 ¶1 More than three months ago, a group of Colorado electors eligible to vote in the Republican presidential primary—both registered Republican and unaffiliated voters (“the Electors”)—filed a lengthy petition in the District Court for the City and County of Denver (“Denver District Court” or “the district court”), asking the court to rule that former President Donald J. Trump (“President Trump”) may not appear on the Colorado Republican presidential primary ballot.
