Sen. Lindsey Graham of South Carolina. Yep, a Republican.
Graham was the only Republican on the Senate Judiciary Committee to have the courage to break away from the GOB - Good Ole Boys - to endorse Sonia Sotomayor's nomination for the Supreme Court. This had to take a lot of guts while sitting next to Jeff Sessions, Alabama; Tom Coburn, Oklahoma; Orrin Hatch, Utah; Charles E. Grassley, Iowa; Jon Kyl, Arizona; and John Cornyn, Texas - six very angry, ignorant, petty men.
