My reading, hands up I may have misread, is that a person barred for insurrection may have that overturned by 2/3 of congress so it doesn't apply unless SCOTUS uphold the bar.
I very much doubt wether he'd obtain such a majority in either house.
If SCOTUS reject Colorado & Maine it looks really bad for SCOTUS on the "Officer' issue in light of originalist thinking apropos court & Congress decisions following the Civil War, or for Federalist thinking apropos the "finding of fact" already determined by 2 x State Supreme Courts.
Would appreciate anyone with better knowlewdge correcting me.
