I'm not necessarily voting for Biden.
I voted for Trump last time, and Biden as President terrifies me almost as much as Hillary did.
However, if you base one's performance specifically on results, I can understand why people will be voting for Biden.
Almost 70% of the country thinks the current administration's handling of the coronavirus was and continues to be deplorable. It's hard to disagree with them on that point.
Additionally, the country is more divided now than ever before. I don't blame Trump for that, but a lot of people do. Sometimes perception is reality.
So if a vote for Biden is a vote for normalcy, it's tempting.
