On a tip from a blog post written by my history-loving colleague, Kurt X. Metzmeier, and featured in the University of Louisville's law faculty blog, I looked it up:
Yes, Barack Obama will be the second United States President with a law degree from Harvard. The first, Rutherford B. Hayes, was elected under circumstances more reminiscent of the 2000 election. One thing is certain: Obama's victory pulls Harvard back into a first place tie with Yale among universities that have conferred law degrees on future Presidents of the United States. Yale's pair? Gerald Ford and Bill Clinton.
