“Dad, I know how much you love me. Promise me you’re going to be all right.” On Stephen Colbert’s show, Joe Biden got emotional while discussing his son’s death and the the possibility of a future in politics. A lot of people are sharing this clip, which makes sense. But I really think part of the story here is how shocked we are when we see a politician acting like a normal human being. (Also worth noting: Colbert is already closing in on Letterman’s career record for emotional moments on The Late Show.)
