Clinton in 2016: Is she or isn’t she?

Hillary Rodham Clinton recently appeared before the U.S. Senate Foreign Relations Committee, which was investigating her role in the tragic events in Benghazi. The former senator and 67th U.S. Secretary of State put on a real-time demonstration of how women might fare in combative situations, by most accounts winning her battle with conservative lawmakers. The performance has led to speculation that Clinton might launch a 2016 presidential campaign.
