Would this have made a difference?

I know it is old news, but I find it very ignorant of people to discriminate based on someones name or race. Where I work now, people in the office are majority republicans and like to throw Obama jokes around a lot. It doesn’t bother me that they make fun of him, it does bother me that a lot of their arguments I find flawed and when they say his name, they elaborate on the HUSSEIN and OBAMA or say OSAMA instead. I find this very childish and wonder that if maybe he weren’t black and his name was John Smith then maybe he would have won by even more of a landslide…. So my question is, who feels that Obama would have won by even more of a landslide if he were white, if not, why?
