You can't flip-flop and be commander-in-chief.

I'm against ObamaCare, which is imposing radical change, and I would be against a conservative imposing radical change.... I don't think right-wing social engineering is any more desirable than left-wing social engineering... I don't think imposing radical change from the right or the left is a very good way for a free society to operate.

Imagine a judicial nominee said 'my experience as a white man makes me better than a Latina woman.' Wouldn't they have to withdraw? New racism is no better than old racism.

I would just say that if Governor Romney would like to give back all the money he’s earned from bankrupting companies and laying off employees over his years at Bain that I would be glad to then listen to him. I’ll bet you $10, not $10,000, that he won’t take the offer.

It may just be because I get homesick, but I have concluded Washington's cherry blossoms are just plain overrated.

If we really care about safety we would close down WikiLeaks. We would treat the people at WikiLeaks as enemy combatants. We would declare that the kind of thing this private did is treason. WikiLeaks is not a fun and games event. WikiLeaks undermines profoundly the ability of the United States to work around the world. Why would you, if you were a foreigner thinking about helping the United States, why would you confide anything to an American when you know that it could end up in The New York Times based on some leak?

I think Donald Trump is very, very cautious about nuclear weapons, and he's seriously concerned. And this might be one of the reasons he wants to deal with Putin carefully, because he's aware of how many nuclear weapons Putin has, and that Russian doctrine is much more open about using nuclear weapons than is American doctrine.
