"Most important, this election is about winning. We need a nominee who can compete in every state, who can bring wandering Democrats and independents back to the fold, and even attract some Republicans. Biden at the top of the ticket is our best bet to win the White House, keep the gains we made in the House, and put the Senate in play. Although 60 years have passed, people still tell me that they are inspired by the words from my father’s inaugural address: "Ask not what your country can do for you. Ask what you can do for your country." Joe Biden embodies those words. He understands that the source of America’s strength — what truly makes us great — are the values and ideals that unite us. That’s what his life of service tells us. That is what his character and decency reflect. That’s why, at this fragile moment for our democracy, Joe Biden is the president we need."
