I thought Biden was more charismatic than Trump. Many boomers watched him work Senate politics well.

perhaps at that time, I'd need to go back and watch the debates again. but covid certainly put a damper on trump's record

Biden called Trump a clown during the debates and he didn't have a response.

Pretty much wrapped it up after that.
