“This campaign can’t only be about me. It must be about us – it must be about what we can do together. This campaign must be the occasion, the vehicle, of your hopes, and your dreams. It will take your time, your energy, and your advice – to push us forward when we’re doing right, and to let us know when we’re not. This campaign has to be about reclaiming the meaning of citizenship, restoring our sense of common purpose, and realizing that few obstacles can withstand the power of millions of voices calling for change.”
—Barack Obama in Springfield, Illinois, announcing his candidacy for the presidency five years ago today. (If you have a few minutes, you should go watch his full speech.)
