Although President Obama shatters the stereotypical presidential image of an old, white guy, he still perpetuates the phenotypic trend of Presidents having dark hair.  Allegedly, there has only been one redheaded President in U.S. history: Thomas Jefferson (though his hair was starting to turn white by the time he took office).  With society becoming a little more and more diverse with time, I don’t doubt that we will have another ginger President.  I just can’t wait for the day when we have a redheaded, black President.
