A second Republican senator, Lisa Murkowski of Alaska, said Sunday she would oppose any vote on a new Supreme Court nominee "this close to" the November 3 presidential election, making a delay more likely. She added her voice to that of Senator Susan Collins of Maine, who went further on Saturday, saying the replacement to late justice Ruth Bader Ginsburg should be made only by the president elected in November. If two more Republican senators join Murkowski and Collins, they could block, or at least delay, a confirmation vote. bbk/bgs
