If people have zero faith that the election was legit (this includes Biden winning but Fox News and other conservative outlets going nuclear), you all think there's a chance we see a state move to leave the union? I don't think the odds are high but definitely think it's possible.
You're more likely to see an unofficial pivot of power towards state and city governments as they take on more responsibilities in response to the federal government doing less and less due to the Republican party's Starve The Beast strategy.
Also this is already happening.
