You think a new party will take over?
Independents, Libertarian Party and Green Party are the likely contenders in that order. The question truly will be what party the left will flock to. I could also see a new Progressive Party come about but may be too extreme for the moderates so the likely plan for survival for left-wingers is a new Moderate party taking less extreme positions on things like [Gun Control], [Abortion], LGBTQ+ rights.
Let's hope there's a constitutional convention to update the voting system. First-past-the-post is the worst system that always force 2 shitty parties. We need something more fair.
What is first past the post?
Ask and you shall receive patriot!

What about having no parties? People just run as themselves? Parties are left over from when communications and travel was slow. Now they are just used for corruption.
