At a recent news conference, President Obama reflected on what caused the 16-day government shutdown, and how another crisis can be avoided in the future. "How business is done in this town has to change," he lectured. "All of us need to stop focusing on the lobbyists and the bloggers and the talking heads on radio and the professional activists who profit from conflict."Those "bloggers" and "talking heads" have every right to say anything they want, of course.
