From the Washington Post:
In a January poll by the Pew Research Center, 53 percent of white people said Obama is "mixed race" and 24 percent said he is black. In contrast, 55 percent of black people said Obama is black and 34 percent said he is mixed.
When filling in his Census form, President Obama passed up the opportunity to check two boxes, and only checked "Black."
