In his presser today, Barack Obama, who is designated as a black man, referred to himself as a "mutt"... perhaps a gentle and self deprecating way of saying that while he is culturally black, he is genetically white as well as black, and who knows, perhaps other races as well. Perhaps this was a way of personalizing the idea that states are not red or blue, we are all "Americans."
And aren't most of us "mutts?
as for me, I'm mostly white but part Native American, and my kids are also 1/4 Asian.
What's your muttness? and are you hypoallergenic?
