Look, I'm not a US citizen, just someone watching this situation from the outside. I'm neither on the democrats nor on the republican side, simply because these terms are more or less meaningless to me.
As this sort of outside observer, though, the answer to the question "Might Trump still win the election?" is very clear to me - he can't, and he won't. Either he will be out of office in January, in which case he will have lost the election. Or he will stay in office due to some fascist power grab that has no relation to how people actually voted, in which case what currently happens in the US will not be remembered as the 2020 election but the American version of Hitler's Machtergreifung. He will still have lost the election, it's just that no one cares.
I hope it'll be the former rather than the latter.
