The problem with this is that Biden already won the popular agenda, so you're imagining a hypothetical 3P agenda is popular.
But it's not because Biden crushed it in 2020.
So your 3P agenda was already posed to the voters and they rejected it.
I'm giving you the benefit of the doubt, throwing all logic aside, and indulging your fantasy of a 3P POTUS...where you're getting mad is everything that comes AFTER a 3P POTUS win, where the complicated and inconvenient rules of governance apply as directed by our Constitution.
That's why I said you never thought through the consequences of a 3P POTUS. If you had even given it 5 minutes of thought, you'd come to the same quandry that I'm posing to you right now...there is no realistic way for a 3P to advance their agenda through a Congress where they control zero seats. So all they can do is rule by executive authority, which is fascist.
So a consequence of voting 3P is fascism because that's the only way that 3P POTUS can govern.
Don't you respect election results?
