Fritz Hollings would be perfectly cast in a role as a snake oil salesman. Oil just oozes from that man whenever he speaks. He's very hard to believe or to take seriously. The Democrats couldn't have picked a better front man (for the GOP, that is).
So Hollings becomes the sacrificial lamb, trotted out to make a complete ass of himself on national television, seconded only by Barbara Boxer, whose chief complaint seems to be that the President wouldn't take a meeting with her on the California energy crisis (which has miraculously evaporated, by the way).
