If I'm president, I'll be a commander-in-chief, not an agitator- in-chief or a divider-in-chief, that I will lead this country in a way that will create greater security and greater safety.

I kind of know what my job is, it's to develop a message that's hopeful and optimistic about the future of the country, to develop ideas that will give people a sense that they can lift up, and to tell them about my leadership skills to make it so.

I'd be wary of simple solutions to complex problems.

Who among us has never looked up into the heavens on a starlit night, lost in wonder at the vastness of space and the beauty of the stars?

It's a complex relationship when your dad happened to be president and you are president and then you have all the amateur psychology that goes on when people try to speculate about motivations.

We have huge national security issues in this country, and the United States Senate ought to be pushing President [Barack] Obama towards the proper policies that right now are a complete disaster based on his policies.

I'm energetic and passionate about the needs - the things we need to fix. I don't feel old, I don't feel like yesterday's news.
