I mostly agree with you. The thing about the precedent, though…this is unprecedented malfeasance. Even the Civil War South didn’t contest Lincoln’s election by trying to set up fake electors and delay the proceedings with violence against Congress enough to kick it to the House - which they would have won, IIRC.
To use Trump’s own words against him - if he doesn’t get indicted and tried and (if he survives long enough) see the inside of a prison, then we won’t really have a country anymore.
