The scene has unfolded at least a dozen times over the past year. In some huge sports arena in a large U.S. city, a second-tier pop singer performs a series of patriotic anthems. After a pause, a burst of horns and the gossamer voice of Frank Sinatra fills the stadium. Start spreading the news ... A maelstrom of red, white, and blue confetti fills the air. Now, a roar surges through the crowd--Rudolph Giuliani has come into view. The standing ovation that greets him might last for a full minute before Giuliani finally cuts it off.
