A couple of other quick points.
Bill Clinton has a Juris Doctor degree from Yale in law, he was a law professor at the University of Arkansas...
Serving as a professor of law at the University of Arkansas is not the same thing as serving as a professor of Constitutional
law at the University of Chicago
. Obama had a specialty in this area, and the U of C is ranked among the finest law schools in the country--Law School 100 ranks it in a tie for third, behind Harvard (first) and Stanford/Yale (tied for second). The University of Arkansas in Fayetteville is prestigious and highly regarded, but came in 85th. To me, this means that Obama probably has a better understanding in great detail of the constitutional mess that has been made by the Bush administration, than Clinton, and the importance of having an SC that can assist in its cleanup through legal clarification.
On the matter of Warren, I would only add that he joined the SC more than 50 years ago, and has been long gone from it. As a political appointee, he was an aberration. Far more typical is the current lineup of 9 justices, whatever one may think of their individual political philosophies. Only Thomas stands out for his lack of juridical experience, and even he had far more to offer from a legal point of view than Clinton:
