During a raucous rally at NRA headquarters, the organization's soon-to-be head touted the importance of their fight. "This is not a battle about gun rights," said James Porter, whose father headed the NRA from 1959 to 1960. "[It's] a culture war." Porter, who says he's determined to strike down anyone trying to "go after our guns," applauded the group's recent victory over President Obama and Congress's gun-control bill. “[You] here in this room are the fighters for freedom. We are the protectors,” he said. Justin Sullivan/Getty An attendee carefully inspects a scope on an assault rifle at the George R. Brown Convention Center.
