So even though I'm focused on the job you elected me to do, and the race may not reach full speed for a year or more, the work of laying the foundation for our campaign must start today. … This will be my final campaign, at least as a candidate. But the cause of making a lasting difference for our families, our communities, and our country has never been about one person. And it will succeed only if we work together.
