Sen. Barack Obama (Ill.), who had anticipated a second consecutive win after his Iowa caucus triumph last Thursday, conceded shortly before 11 p.m. "We always knew our climb would be steep," he told supporters, a day after he had confidently told backers that he was "riding a wave" to a win here. Former senator John Edwards (N.C.) placed a distant third, followed by New Mexico Gov. Bill Richardson.
