President Elect Obama is a public official and his daughter's are also in the public eye. I don't think that it is a PR stunt or anything of the sort but I do feel is that he gave the American people what they would have found out about later. Then the letter would have been in "headlines" and everyone would have been really interested. President Elect Obama's life is an open book as well as his family and sharing this letter with us is not a bad thing. Thankfully some of us had Father's that loved us enough to write a letter and for the other's let this be a lesson.
To add another comment....... since the election and event's leading up to the election; I have never in my life seen and heard so much racism. I've always been pround to be a American but the behavior that I've seen recently is embarassing.
