The other represents George Steinbrenner. Ridiculously rich people who live in Manhattan root for the Yankees. The Mets are located in Queens, where real people predominate. Yankee fans don't even know where Queens is. Luckily their chauffeurs do, or Yankee fans would never be able to reach either city airport.
Statistics tell the story.
As I believe Al Gore pointed out in one of the debates, the Yankees are the team of HMOs, Big Oil and Big Tobacco. Lacking the foresight to inherit trust funds, they have actual jobs. They don't go to work in pinstripes and they don't send their baseball team out in them, either. Unlike Yankees fans, they do not expect to win every year, and they don't throw tantrums or complain bitterly to their butlers in those off years when they don't win the pennant. Rooting for the Yankees has the same excitement level as rooting for Merrill Lynch or betting that the sun will come up in the morning.
