In a crowded field of Democratic presidential contenders, former Colorado Gov. John Hickenlooper makes an impression on voters as a genuine candidate, even if he's a bit quirky. He colors outside the lines of the political conventions -- a geologist by training, a brewer and restauranteur by profession, and a politician only later in life.  In this episode, he talks about his temper as a child, his pragmatic approach to politics, and how he's managed to succeed in a people-driven business despite a condition commonly known as face blindness, a condition that keeps him from recognizing familiar faces.
