Manchester, New Hampshire (CNN) – Five things we learned at the debate:
1) Michele Bachmann is now a candidate for president. The congresswoman from Minnesota was the only person on the stage who was not officially a candidate at the start of the debate. That changed minutes into the debate, when Bachmann told CNN's John King, the moderator of the debate that "I just want to make an announcement here for you, John, on CNN tonight. I filed today my paperwork to seek the office of the presidency of the United States today. And I'll very soon be making my formal announcement."
