Our four greatest presidents have things in common. Harry Truman and Abraham Lincoln were men of the people, men with "common man roots" and understanding of the mind of the common man and woman. Both Teddy Roosevelt and FDR were from the country's upper crust, but had real physical handicaps which left them with an understanding of what it feels like to struggle That struggle gave them some real understanding of and empathy for others.

I believe that this same characteristic will make Joe Biden a member of the top 5.
