Unfortunately, the political system in the US has been untenable since Citizens United. We only have two viable parties, and both receive their funding from the same sources. I regularly send letters to my Democrat senators and representative, and based on the responses I get back, I can only assume Republicans and Democrat are the same party - they just wear different fashion.
The powers at be are waiting for a Reichstag fire. But, (luckily) Americans are too lazy for that.
