Massachusetts Sen. Elizabeth Warren has answered the question time and time again: Will you run for president in 2016? There is no doubt she will continue to have to field such inquiries following an appearance on Huffington Post Live. In support of her new book, A Fighting Chance, Warren was interviewed in Boston’s Old South Meeting House (as host Ryan Grim points out, is the scene of the genuine and original Tea Party). Also interviewed about his book, Capitol in the Twenty-First Century, is economist Thomas Piketty. In the interview, Warren is warm, engaging, relatable and holds a great command of the topics. The show is likely to spur more “Warren 2016” talk. Hillary beware.
