Sometimes people just feel as if we want to try something to see if we can shake things up.

The amount of interaction, the amount of understanding that exists in your generation among people of different races and different creeds and different colors is unprecedented. And by the way, that goes - that cuts across party lines, that cuts across partisan lines.

If I'm president, some day, young kids will look at the world differently. They will say, I could be president some day. They couldn't have said that before I came along. The world will see the United States in a different context, as a country of true opportunity for all.

Civility also requires relearning how to disagree without being disagreeable. Surely you can question my policies without questioning my faith or, for that matter, my citizenship.

As you get older, your mind gets a little more set. And it needs the poking and prodding and breaking through of stereotypes that I think young people provide.

I think that there is a particular mindset that was on display in the run-up to the Iraq war that continues to this day. Some of the folks who were involved in that decision either don't remember what they said or are entirely unapologetic about the results, but that views the Middle East as a place where force and intimidation will deliver on the security interests that we have, and that it is not possible for us to at least test the possibility of diplomacy.

We need earmark reform, and when I'm President, I will go line by line to make sure that we are not spending money unwisely.
