2020, the election campaigns have begun

I've a feeling that people in the USA are a good bit more left leaning than the common wisdom says they are, so complaints about left leaning candidates not interesting the 'centrists' aren't that big a deal.

That said, it's irrelevant who becomes president if the Republicans aren't ousted from power in all branches of the federal government, and preferably also take a heavy clobbering at the state and local level. And I don't just mean in votes.

Fail to do that and American democracy is likely to stop being a thing for quite a while, and we can see that Russia at least has a lot of power over the Republicans right now, and may translate that into the future even if the current president is replaced.
