This also happened before he was a sitting president, so all the stuff about “Bush Iraq war crimes” and “Nixon’s burglary” and similar historical presidential baggage is mostly irrelevant, at least in terms of new precedent.
The social/civil consequences of this sort of criminal indictment before election is enough to kill a presidential campaign and has enough times in history. As it should be.
This is behaviour before/after presidency when the stakes are far lower.
Trump is a fundamentally different player than Bush or Nixon. They were establishment in times the establishment wasn't nearly as hated as it is now.
This just plays to Trump's strength as the ultimate rebel.
In terms of game theory, this is a very different game than Nixon or Bush.
Trump annihilated the Bush Legacy, and is hated by both sides of the establishment.
Trump is part of "the establishment" himself. And that he can bullshit people like you into believing otherwise is part of his superpower as a lifelong pathologic liar.
Just in case, I am hereby declaring my candidacy for the President of the United States for the upcoming election and all future elections in my lifetime.
