Ralph G. Neas, president of the liberal People for the American Way, said: “With every day that passes, it becomes more clear that confirming John Roberts would mean replacing Sandra Day O’Connor with someone who viewed her as an obstacle to the ultra-conservative movement, which he had helped lead when he was with the Reagan and first Bush administration.” Neas’s organization has not declared outright opposition to Roberts, he said, but views the nomination with increased concern in light of recent revelations about his role.
