It's being called "Silent Night."
The switch in format seemed to give Mitt Romney an edge.
Steve Battaglio of TV Guide magazine said, "Gingrich was extremely unhappy about this rule because the crowd has been an effective weapon for him. He knows how to get them to respond. He seemed off balance, he seemed off the game last night."
The issue sparked a debate on The View Tuesday morning.
Elisabeth Hasselbeck said, "I think the American people sitting there have a right to express how they feel peacefully."
Gingrich had this to say on Fox News, "I wish in retrospect I had protested when Brian Williams took them out of it because I think it's wrong. And I think he took them out of it because the media is terrified that they're going to side with the candidates against the media."
Meanwhile, Romney finally released his tax returns.
They show he made $42.5 million over the past two years and will pay $6.2 million in taxes, for a tax rate of 13.9 percent in 2010, and 15.4 percent this year. It's a rate far below that of most working Americans.
