<p>Crimsonbulldog is correct, I think, based on what I’ve heard from every Yale graduate I’ve ever met. He touches on a reason why I think perhaps there’s a fourth major reason Yalies choose Yale (in addition to the three I posted above). See the article at <a href=“http://en.wikipedia.org/wiki/Yale_University[/url]”>http://en.wikipedia.org/wiki/Yale_University</a> - it says that the reason Yale dominates national politics, according to New York Times correspondent Elisabeth Bumiller and Atlantic Monthly correspondent James Fallows, because of “the culture of community and cooperation that exists between students, faculty and administration, which downplays self-interest and reinforces commitment to others.”</p>
