Jenkins: Roberts (a former law clerk for Rehnquist) is his natural heir, and I believe that Rehnquist would be largely satisfied with how things are going. I don't think the court is operating in a significantly different way than it operated under Rehnquist. The thing that has me scratching my head is what he would say about the Affordable Health Care Act decision (in June, upholding the law championed by President Obama), how he would have voted. I don't think Rehnquist would have voted as his successor voted.
We'll just have to see how Roberts evolves in the future, or if he evolves as a leader of the court. But Rehnquist overall would look at the court and be satisfied with his legacy. He really brought that about and it was built upon by the other justices, like Scalia. But Rehnquist was the guy who made it acceptable for all those men and women to come later and be partisans.
