Colorado voters sought to keep former President Donald Trump off the state’s presidential primary ballot, alleging that Section 3 of the Fourteenth Amendment disqualified him after the events of January 6, 2021. The Colorado trial court found that he had engaged in insurrection but denied the petition on other grounds. The Colorado Supreme Court ordered the Secretary of State to exclude him from the ballot. The Supreme Court of the United States reversed. It held that the Constitution assigns Congress responsibility for enforcing Section 3 against federal officeholders and candidates, and that the States may not independently enforce the provision against candidates for federal office, particularly the Presidency. The Court emphasized the national need for a uniform rule rather than conflicting state determinations. The decision restored Trump’s eligibility for Colorado’s primary ballot. Several justices concurred separately, including disagreement about how broadly the Court should address enforcement limits beyond the question presented.
