Look, being president of the United States is the toughest job in the world and I can tell you, as someone who has worked with Secretary Clinton and competed against her that she is a tough person who is ready to do this job.

Triangulation is not a strategy that will move America forward.

I think America is moving to a much more connected, inclusive and compassionate place.

Our parents and grandparents understood this truth deeply. They believed - as we do - that to create jobs, a modern economy requires modern investments: educating, innovating and rebuilding for our children's future. Building an economy to last, from the middle class up, not from the billionaires down.

We are going to be able to defeat ISIS on the ground there, as well as in this world, because of the Muslim Americans in our country and throughout the world who understand that this brutal and barbaric group is perverting the name of a great world religion.

But we should not lose sight of how far we are coming and what a big hole we were left by George W. Bush.

A stronger middle class is not the consequence of economic growth. A stronger middle class is the cause of economic growth.
