Stanford vs. Harvard

I thought it was interesting that Barack Obama and Yukio Hatoyama both went to such prestigious universities in the US. I wonder if they felt any old rivalries? Traditionally, Harvard is a rival of Yale rather than Stanford - although all top-tier universities probably have some level of rivalry with each other. My university didn't really have rivalries, except maybe at the medical school. That's what happens when you go to a school without many good sports teams!
