No matter how much Obama continues his sudden changes on issues many still think they know who he will appoint to the Supreme Court

Eugene Volokh tells Time magazine:

And Obama's run to the center surely won't stop conservatives from using the specter of a Democratic-appointed Supreme Court to try to rally support. "Its pretty clear that if he's elected and Justice Scalia or Kennedy retires that he's going to appoint someone who's very likely to reverse [the gun control decision]," says Eugene Volokh, a professor at the UCLA School of Law. Given how Obama has been responding to the recent Supreme Court decisions, however, you're not likely to hear him talking about appointing liberal justices much between now and November.
