Hmmm. I wonder if somebody DOES have a storage unit, garage, etc. of all of Barry's old letters, college stuff, etc. Being the malignant narcissist that he is - I would almost bet on it. Thinking ahead not only to being president some day, but on making history as the first black president, etc., and wanting it all in a presidential library some day.
Although perhaps his handlers were able to override his pride, and destroyed it all.
With his narcissism I would bet he overrules all of his “handlers.”
