McCain warms to test ban

Senator John McCain, who helped vote down U.S. ratification of a nuclear test ban treaty 10 years ago, said he would now consider supporting it. McCain has embraced Obama's goal of eliminating all the world's nuclear weapons and said that a global test ban would be a step forward if it were implemented prudently. He said he still had some concerns ("The devil is in the details") but "if we could get it done, if it is acceptable, then it is a step forward on the path to the president's goal and mine of a nuclear free world."  Daryl Kimball, executive director of the Ploughshares-funded Arms Control Association, welcomed Senator McCain's comments. "John McCain is one of the only Republican senators who is independent-minded enough to break out of the partisan dividing lines on this issue.  He has the gravitas to influence others in the caucus."
