Fitness or lack thereof is left to the voters, hence an incompetent and senile Biden.The folly would be to elect him first. Fitness must be determined. I believe some states will apply 14A, at the first felony conviction. It stands, unless someone sues and wins.
Trump is not charged with insurrection. There would be no cause to even invoke the 14th Amendment. You folks are just scared silly and no longer capable of rational thought.
