Is there something stopping people from doing these things and voting for the person who isn't a literal psychopath that will crash the economy and will gleefully escalate WW3
I don't think voting really matters. Do it if you want. I think we're going to end up with a similar result (I mean ... look at Trump and the Scamedmic), but I do honestly hope you're right. I wish we could vote our way out of this. I don't share your optimism, but I don't think it does any harm if you want to do so. Just be prepared in either case.
