In other news from Washington, Samuel Alito was sworn in to the Supreme Court Tuesday after he was approved in a Senate vote divided almost entirely along party lines. The final vote was 58 to 42. All but one Republican — Senator Lincoln Chafee of Rhode Island — voted for Alito’s nomination. All but four Democrats — Senators Ben Nelson of Nebraska, Kent Conrad of North Dakota, Tim Johnson of South Dakota and Robert Byrd of West Virginia voted against him. Alito joins the court with less Senate support than any Supreme Court justice in the past century besides Clarence Thomas.
