National Review Online just caught up with Glenn Beck backstage at the FreedomWorks conference in Washington, minutes after the talk-show host made a surprise appearance. Beck tells us that he “has no idea” about how many people will show up at his event tomorrow, but remains hopeful about turnout. He also challenges his critics to “listen to the message,” and not to misinterpret the rally. “Read the sign,” he says. “This is about restoring hope and honor.”
