The Colorado Ruling Is a Rebuke for the Ages

How can it be that nearly three years after Donald Trump incited an insurrection to stay in office, interfering with the peaceful transfer of power for the first time in American history, he remains eligible for a second term as president? In a stunning ruling on Tuesday night, the Colorado Supreme Court answered that question: He can’t be allowed to run again.

The Colorado court’s 133-page decision said that he is not eligible to be on the state’s ballot for president under Section 3 of the 14th Amendment, which bars from public office anyone who swore an oath to the Constitution and then engaged in or aided an insurrection against it. The Jan. 6, 2021, attack on the Capitol was an insurrection, the court found, upholding part of a trial judge’s ruling from last month, and Mr. Trump engaged in it.
