No matter what, the US Federal government is going to be ruled by a single party, the only question is: will it be the liberal party or the Trump cultists.
Edit: every time I comment this I get downvoted, which I think is odd because it’s irrefutable. The US was a two party system, but one of those two parties has gone completely bat shit insane, leaving only one viable political party in the US. If the bat shit party doesn’t take power, that leaves only one other option. The math is pretty simple here, so I don’t get how this is controversial. Even if you think a new second party will emerge, that’s going to take some time, and in the meantime there will be one political party in control.
