Trump needs to be charged as being an insurrectionist or aiding and abetting, go through with the trial, due process. This should be done at the federal level
It can't be done at the federal level since each state has the sole authority and right to determine how elections are run in each of the several states.
Trump could be allowed on the ballot, but the secretary of state could refuse Trump’s slate of electors.
Shades of the "Green Bay Sweep". That idea is the equivalent of VP Pence rejecting certified elector votes, disenfranchising voters, and replacing with a Secretary of State doing the same. I think this is why the insurrectionist candidate must be disqualified prior to an election.
