"In January 2008, I joined my uncle, Senator Edward M. Kennedy, to endorse Barack Obama for president. We believed America was ready for a new generation of leadership, for a president who would inspire us, as my father did, to believe in the power of ordinary people to do extraordinary things, and the nobility of public service. We face a very different world today. President Trump has done immense damage to our institutions, exploited our differences, and shredded our credibility around the world. I am excited by the Democratic candidates and the ideas they have put forward. But this year, it’s not just policy proposals that are on the ballot. Our fundamental values are at stake as never before in my lifetime."
