I live in a purple suburb and I’ve only seen one Biden yard sign and maybe 2 bumper stickers at most.  I’ve seen more “Any sane human 2020” signs and a “Meteor Strike 2020” bumper sticker.    I’d take those to mean they hate Trump but are too embarrassed to publicly back Biden. There is ZERO enthusiasm for Biden.  I don’t see how that can beat Trump outside of massive cheating.
