Not everybody in America views the election as a game, or as a binary choice. Most people do, for sure, but not all. It's not Duke-UNC or Yankees-Red Sox for everybody. Therefore there will always be a very small minority of voters who don't see it as concretely as "I need to automatically vote for Biden if I don't like Trump." (And yes, I know that, practically speaking, it really is that simple, so you don't need to remind me in this thread or send me PMs to tell me how stupid I am. Thanks.)
"We are not provided with wisdom, we must discover it for ourselves, after a journey through the wilderness which no one else can take for us, an effort which no one can spare us, for our wisdom is the point of view from which we come at last to regard the world." --M. Proust
