This is simply politically driven nonsense played by the most partisan Secretary of State that Colorado has ever known. She's gotten her friends to register as republicans and pretend to be "never Trumpers". Innocent until proven makes it clear that you cannot punish someone for something until you've proven it. This is going nowhere, and everybody here knows it. Trump will be on the primary ballots in every state. He's not even been indicted for "insurrection" let alone convicted after its been proven.
The 14th Amendment is silent on indictment or criminal conviction.
