I would vote no matter what (assuming I am legally allowed to vote). You have lots of local elections and initiatives that are also on the ballot, plus what if depressed participation causes more “safe” blue states to swing in the wrong direction? Less margin means Trump will challenge the integrity of the election and try to declare he is the winner in more places.
Yes, but I think the point is that strong man types do appeal to a certain demographic that they are trying to influence, not that it appeals or should appeal to themselves or the general population
