On the eve of the Jan. 8 New Hampshire primary, the usually steely Clinton becomes emotional during a stop at a Portsmouth diner. Asked how she keeps it together amid the rigors of daily campaigning, she says: “It’s not easy, and I couldn’t do it if I didn’t passionately believe it was the right thing to do.” Then, her eyes welling and her voice breaking, she continues: “You know, this is very personal for me. It’s not just political.” (Elise Amendola / Associated Press)
