Im a centrist, far from far-left. I believe Trump will be beaten handily but will do everything in his power to stay in office. He has disgracefully been attempting to suppress the vote and has a small possibility of winning because of it. My likely scenario is that trump may be ahead election night but will ultimately lose because of mailin voting. He will challenge the validity of whatever happens because he is a divisive fool and has no integrity. His base, largely ignorant fools (the fundamentalists being the largest body of ignorance in our country) will support whatever he does. Get ready for a stormy ride through 1-20-2001, I dont think he will leave peacefully. The 2018 election showed suburban women going blue and I think that election is a reflection of how this one will go. I expect the Dems to take control of the Senate as well. I see the country as very dissatisfied with his cult of personality rule. His base will stand by him but this is 30-35% of the populace. Few on the fence will vote Red. Anecdotally, I know many republicans and conservatives who are voting for Biden, even a conservative Catholic deacon who runs a parish. I think the American people will largely see him for the corrupt conman he is.
You don't offer much analysis, but I guess I appreciate whatever substantial points you make but I am afraid not your polemics. In essence, in America today, there are two populist movements happening right now. One that is new age conservativism and one that is new age socialism/communism. They both have different policy agendas but a common end, which is to undo the neo-liberal destruction of America through globalization of finance/production, outsourcing, open borders, urbanization and sanctuary cities and so on since the time of Clinton through Obama. For the conservative movement, the policy agenda focuses in on manufacturing, trade, law and order and equality of opportunity, and for the new left, it is almost all about redistribution (medicare for all, free college, UBI, defund the police for social purposes) and equality of outcomes.
Biden is in a tough spot, because at the moment centrist means a step back to the neo-liberal policies that created this mess to begin with and would alienate the left's populism (led by Sanders). Being a centrist is a losing strategy in current times, but the ploy of Trump to paint Biden as far left also checkmates Biden, who is now increasingly trying to move to the center more recently (his stand on defunding the police, law and order and medicare for all and other social protections). By moving more to the center, Biden will keep the wine sipping, suburban women but will lose the Bernie Bros. By moving further left, Biden will lose the suburban women, independents and a part of the black vote. In essence, check mate.
I don't think mail in voting is going to affect the outcome in already blue and red states. Where it can be troublesome is in those swing states that have a Democrat Governor and the system put in place to ensure accuracy and accountability.
