GEORGE KORDA: Political supporters candidates can (and can’t) count on. “When candidates for elected office ask me if I have any advice as they enter into a political campaign, I offer them a practical suggestion having spent most of my adult life working in and observing political campaigns. Get yourself a small notebook, I say to them, one that will fit in your coat pocket. When someone of whom you’re unsure tells you they’re solidly in your corner, take the notebook from your pocket and start writing down their name, saying you’ll be proud to list them as a supporter. When you do that, I add, one of several things will happen.”
