Honestly, I am pretty concerned that Biden is going to win the election. A lot of people really want all this madness to end and return to normal, and they see Biden as being a return to those "normal times under Obama". Heck, one of his ads is him pointing out how he was with Obama for both terms and all that. Alongside some of Trump's more questionable statements, like failing to properly condemn white supremacy and refusal to properly release his tax payments (unlike Biden), it may cause people to view Trump as being shady and lacking integrity, focused more on his image than on uniting the country (at least, that's the case based on reactions from family and friends).
Couple that with the media just continuing to hammer the notion of Trump being evil over and over again, alongside people generally being more willing to just gobble up the reports rather than do research themselves, and I fear that we will be seeing Biden and Harris in the White House soon.
