My first thought was James Caan. Then I thought of Clint Eastwood, but last night, while watching My Name is Earl, a spark went off in my imagination about it being Craig T. Nelson. This is PURE speculation, and kind of fun and for entertainment purposes.
What are your thoughts, if it is an actor?
Here's a fun thought! Have you thought of John Voight? He is a great actor, and he kinda sounds and looks like he could pass as Biden. He is VERY pro Trump so he would play the role with his heart! This may sound creepy but if you look through photos..... Similar ear lobes, teeth, and hairline!
That could make sense too. Is he light on his feet, almost running up the stairs onto a plane?
