It is not known how many people in the United States write to Obama and how many different topics are presented to him.  It’s clear that he cannot read all the letters and deal with everything because he wouldn’t be able to fit it into a 24-hour day or a 365-day year.  What is certain is that his advisors, backed up by their computers, electronic equipment and cell, answer all the letters.  Their contents are recorded and there are pre-written answers supported by the multiple declarations of the new president during his campaign to be nominated and elected.
