Per Curiam.  A group of Colorado voters contends that Section 3 of the Fourteenth Amendment to the Constitution prohibits former President Donald J. Trump, who seeks the Presidential nomination of the Republican Party in this year’s election, from becoming President again. The Colorado Supreme Court agreed with that contention. It ordered the Colorado secretary of state to exclude the former President from the Republican primary ballot in the State and to disregard any write-in votes that Colorado voters might cast for him.

 Former President Trump challenges that decision on several grounds. Because the Constitution makes Congress, rather than the States, responsible for enforcing Section 3 against federal officeholders and candidates, we reverse.
