Washington loves and adores moderates, and Graham deserves attention for breaking with knee-jerk conservatives on issues like immigration where he backed his friend, John McCain's, plan for a path to legalization for illegal immigrants. That's a plan McCain himself would later abandon.
So it shouldn't come as a surprise that Graham is making moderate noises about being undecided on Sotomayor. He did the same thing during the Clinton impreachment hearings--before voting for impeachment and becoming one of the floor managers of the fight for impeachment. I suspect, and it's just a guess, that this time he will vote for Sotomayor. I think he's smart enough to know that Hispanic voters are going to remember who voted against the first Latina justice. And I think, like Orin Hatch, who supported Clinton's nominees to the Supreme Court, Ruth Bader Ginsburg and Stephen Breyer, Graham will be inclined to defer to the president on judicial matters. This time Lindsey, I bet, really will be a moderate. That's one of the few sources of tension in this hearing thus far.
