During the campaign, I supported and encouraged the Clinton campaign strategy, but in hindsight, I lost track of one of the core lessons of Obama’s success—campaigns are about telling the American people a story—a story about where we are, where we are going, and why you are the right person, and your opponent is the wrong person, to take the country there. It’s a story that needs to be compelling, but also easily understood, and then driven home by the candidate and the campaign with relentless discipline.
