This was one of the tasks we set forth at the beginning of this campaign – to continue the long march of those who came before us, a march for a more just, more equal, more free, more caring and more prosperous America. I chose to run for the presidency at this moment in history because I believe deeply that we cannot solve the challenges of our time unless we solve them together – unless we perfect our union by understanding that we may have different stories, but we hold common hopes; that we may not look the same and we may not have come from the same place, but we all want to move in the same direction – towards a better future for of children and our grandchildren.
