No one should ever call the President of the United States a liar, especially during a live speech. S.C. Rep. Joe Wilson lost his mind yesterday when he did just that, which would have made sense if in fact he had said that to Gov. Sanford, Lt. Gov. Bauer and former Chair of the State Board of Education Kristin Maguire -- all proven liars. The only difference is that they happen to be Republican and white. It is so sad when a Congressman can't keep his racism in check.
