It was a pretty solid setup when everyone wanted it to succeed. We will get a few more safeties put in place via statute after this experience, of course, but what really needs to happen is meaningful improvements to the Constitution. We know enough now to spot plenty of weak points which could be addressed. When I'm feeling particularly spicy I think a Constitutional Convention would be seriously awesome. But then I think of the possible outcomes and I'm not so sure. Were the majority of the population acting in good faith, I'd feel better about it.
There is no easy way out of this mess. There has to be some faith in the overall good will of the people, but if Russia and other societies are any indicator in a modern world, it will take the US getting a lot shittier, with more people dying in protests, more people losing their careers and their homes, and the middle class in breadlines.
We need a different voting system, we need the structure of Congress gutted, and we need a far less powerful presidency.
I thought I made it clear that I don't generally think that would be a good idea. I think it would be interesting, which I sometimes think might be worth the risk. Certainly discontent with the status quo is a broadly held sentiment not at all unique to the current right wing.
