As far as I'm concerned, Bush is just that, a bush. He will never be something as strong as a tree, even if he does become presidential elect. His name is a given name. Money can't buy you a true name, even though it may buy a seat as the president.
Lead Belly and Bush shouldn't even cross paths at this day and age. Lead Belly happened back then. Murder, slavery, deceit happened at that time. Things are different today. You can't take that back. Period.
Too much to say in a posted note/letter.
