This conveniently ignores that Trump's situation is predicated on actual behavior during an actual honest-to-goodness insurrection (yes, it has been adjudicated an insurrection many times at this point, see Jan 6 convictions). He publicly and directly addressed the terrorist group Proud Boys in televised remarks, the group at the heart of the insurrection, whose leaders are now jailed for it, calling them to attention to "stand by". No one doubts he failed his constitutional duty to protect the transfer of power. He disavows it to this day! When they invaded the capitol in an insurrection, that made it a lot harder for some other presidential candidate to come to the table with the same resume for being barred from the ballot. If I were any candidate in the future and the bar were this high, I'd rest easy every day of the week.
GTFO with this slippery slope bullshit.
