Some of Rosen’s comments in the interview are a little odd, as when he said that Sandra Day O’Connor "seemed to have a unique ability to put her finger on the pulse of the median voter with exquisite precision and express it more precisely than Bill Frist or Harry Reid" and when he suggests that Chief Justice Roberts is no "libertarian radical" willing to pull the trigger on Roe. I agree that the CJ is no libertarian radical, but libertarianism seems to me to be the essence of much of the "pro-choice," "pro-self-definition" jurisprudence committed by members of the Supreme Court. Libertarians would, I think, vote to uphold Roe, so Rosen’s choice of an appellation seems off.
Update: I stand (somewhat) corrected by John Mosers comment below. For a summary of the libertarian case against Roe, go here. On the other hand, the, er. vulgar libertarianism of my students generally tends in a pro-choice direction, whatever may be the case with their sophisticated and officially Libertarian brethren.
