That is interesting. Can you offer a citation?
Counterintuitive as it seems, there actually is a surprisingly plausible case to be made that the President isn't an officer of the United States.
I believe some states do only allow people to be on ballots if they are judged to meet the criteria for the position, but could be wrong.
One doesn't need to be convicted of insurrection to be disqualified; not many people were formally tried over the Civil War, but were declared ineligible for office.
Also, the claim of that judges in other states will do this to Democratic politicians as payback doesn't make much sense. Even if someone thinks Trump didn't engage in insurrection (I am presently inclined to believe he did), it's undeniable there's at least an actual case to be made; what case is there for other politicians, particularly any Democratic ones? I've seen a few people try to draw parallels with Black Lives Matters riots, but however much property damage might have been caused or general disruption, none of it was at the federal government that I am aware of, save for perhaps
the courthouse siege in Portland and the Capitol Hill Autonomous Zone (at least any that continued to resist after law enforcement moved in for the latter). I am not aware of any nationally elected Democratic politicians who could be construed to have engaged in those things in the way Trump can be associated with January 6.
I suppose there's nothing technically stopping any judge from giving any ruling they want no matter how random (aside from being overturned in appeals), but even the most partisan of judges needs at least
some level of plausibility, and when people bring up this objection I don't see them ever give examples of any Democratic politicians that could be plausibly argued to have run afoul of the Disqualification Clause in the way one can make an argument for Trump.
Probably.
