Warren G. Harding was corrupt, as was Richard M. Nixon. Bill Clinton and John F. Kennedy were like blind golfers, looking for a hole, any hole, every hole. Woodrow Wilson and Franklin Roosevelt were power-mad narcissists convinced they knew best how everyone else should live. Jimmy Carter was clueless. But as we approach the 100-year anniversary of the first of these men to serve as president, all have been lapped in debasing their office by its current occupant: Barack Obama.
