Yes we can!

. A few weeks ago, no one imagined that we'd have accomplished what we did here tonight. For most of this campaign, we were far behind, and we always knew our climb would be steep. But in record numbers, you came out and spoke up for change. And with your voices and your votes, you made it clear that at this moment – in this election – there is something happening in America. There is something happening when men and women in Des Moines and Davenport; in Lebanon and Concord come out in the snows of January to wait in lines that stretch block after block because they believe in what this country can be. There is something happening when Americans who are young in age and in spirit – who have never before participated in politics – turn out in numbers we've never seen because they know in their hearts that this time must be different. There is something happening when people vote not just for the party they belong to but the hopes they hold in common
