John Roberts, Jr to become a Supreme

[BigV]

I have a question.

I imagine that the prerequisites for judge-ships (not only SCOTUS) in our country do not include being a lawyer, but certainly that helps, since that is the most likely path to a thorough knowledge of the law. John Roberts Jr. is a lawyer, not a judge, right? Here's my question. In the modern history of the Supreme Court, how many Supreme Court Justices were not judges before their nomination and confirmation?

I ask because I could not find anything like the answer in my brief search. Also, there's a lot of talk about JRJ thinks this and JRJ thinks that and "how would he rule?" Really, we know very little about his thoughts on a given subject if we base our opinions on the side he was arguing. I agree with the earlier posts that a good lawyer (which by all accounts, JRJ is), will diligently serve his client, and the lawyers personal feelings are largely irrelevant.

There is a very short paper trail of HIS decisions and opinions, unlike a judge from a lower court that may have a long list of actual performance as a judge to examine. Your thoughts?
