This is the only acceptable reason, in my book, to vote for Biden. I get it that you hate the other candidate so much that you'd vote for whoever is running against them. In 2016, Trump was not my choice at all but I hate HRC so much that I voted against her. Yes, I could have voted 3rd or 4th party but I wanted that vote against her to count.I would think that most are voting AGAINST Trump and not voting for Biden.
This year, for the first time since I started voting, I voted straight down the red line and I voted FOR Trump this time!
