The point about the Twenty-Second Amendment is very important. I’m just as conflicted about using the Fourteenth Amendment to disqualify Trump. But if a candidate (or especially a court) can just ignore the plain text of a passage of the Constitution concerning qualification for office, then he/she (it) can ignore ANY passage.

“Trump is immensely popular and it would be in democratic to remove him from the ballot!”

Now substitute “No person shall … hold any office who … shall have engaged in insurrection or rebellion“ with “No person shall be elected to the office of the President more than twice.” The excuse can neuter them both.
