Being convicted of a crime doesn't disqualify anyone; people have run for President from prison. And most of the people who attacked Congress on Jan. 6 would not be disqualified for it even if they are convicted of a crime for it.
Disqualification is not a criminal punishment. It's not a crime to be 34 years old, for example, or to have been born in another country. But those are still disqualifications, and they are and always have been enforced by the states.
"High crimes and misdemeanors" is a term of art that refers to acts committed by a public official which, while not necessarily a crime in themselves, are a violation of public trust.
For example, a president that accepted a foreign title of nobility without Congressional consent would have committed a high crime, but they couldn't be hauled into a criminal court for it.
The only thing Congress can do is remove Trump's disqualification under the 14th amendment. They can't decide whether he's disqualified in the first place.
The 14th amendment doesn't require impeachment or criminal conviction, though. It's a completely different disqualification provision from impeachment.
For example, members of Congress cannot be impeached, but they can be disqualified under the 14th amendment. It makes no sense to roll impeachment and the 14th amendment into the same category of disqualification.
All fair points that still ignore the guy who tried to overthrow the country where absolutely nothing was done about him, to hold him accountable.
If the feds are saying only they can protect the country from all enemies orange and domestic, there’s about 80 million active voters who might, uh, decidedly disagree. As opposed to some other adverb.
Point is that if the three blue states disqualify without a federal ruling and that stands, then you can bet a bunch of red states will declare Biden disqualified because he stole the election or some crap.
The place to direct frustration is the federal government for failing to make the requisite determination. Not at the unanimous supreme court decision that prevents chaotic behavior by the states with respect to federal races. There should be consistency state to state as to whether a candidate is fundamentally qualified or not.
