In 2010, the New York Times’ Supreme Court reporter, Adam Liptak, wrote an article entitled “Court Under Roberts Is Most Conservative in Decades.” He noted that in its first five years, Chief Justice John Roberts’ court had rendered conservative decisions 58 percent of the time, and in the 2008 term 65 percent, the highest rate in a half-century. The court was “the most conservative one in living memory.” Republicans, who have been trying to move the court to the right since Nixon was president, finally had put into place a rock-solid conservative majority.
