Obama did talk about his mother and grandparents being white or caucasion if prefer, It is the media running with the African American theme. No other president has had to get up there and state thier race why should he? How about this, his race, my race, your race, OUR race is the HUMAN RACE! I myself agree that everyone is targeting the fact that he is African American, and I feel well he is half white also, but like I said  it is not him doing it , it is the media.Not once have I seen or heard him say I am just African American.
