The Colorado Supreme Court has taken the extraordinary step of barring Donald Trump from the state’s 2024 presidential ballot.

By a vote of 4-3, the court’s majority ruled that Trump’s conduct related to the January 6th Capitol attack violates the 14th Amendment’s prohibition on insurrectionists running for office. This marks the first time in history that a state has officially disqualified a candidate under that provision.

However, the Colorado Supreme Court’s decision has been stayed until January 4th to allow Trump’s campaign to appeal to the US Supreme Court.
