Context: Trump's lawyers are in front of the Supreme Court arguing that presidents cannot be prosecuted for any crimes they commit while in office.
Who knows how the Calvinball refs will decide this one, but if they go Trump's way, Biden has literally no excuse not to assassinate his political rivals.
If they believe he will become a dictator (the trick here is I don't think they do) then there would need to be some kind of resistance and civil war in response, right? So kill the future dictator and deal with the possible civil war while you're officially in charge of the nation.
this is all just sophistry, the ones in power don't think he'll be a dictator they just think that's what the rubes need to hear
