This is... one of the great tragedies of the Bush administration. The more successful they’ve been at intercepting and stopping bad guys, the less proof there is that we’re in danger... it’s almost like they should every once in a while have allowed an attack to get through just to remind us.

You know, presidents have to be disciplined, and in that sense Hillary Clinton is probably better trained to be president, just because she's the most corrupt person to ever get the nomination of a major party.

I think Putin has already gotten used to the idea of Obama and his secretary of state, John Kerry, making noise - it just doesn't seem to impress Moscow at all.

Change is healthy and useful. It has to be fought for most of the time. It's not inevitable. It takes real leadership and real effort. But I think it's really important not to take yourself too seriously. Dwight Eisenhower used to have a rule that you should always take your job seriously but not yourself.

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.

I think if you have mandatory carbon caps combined with a trading system, much like we did with sulfur, and if you have a tax-incentive program for investing in the solutions, that there's a package there that's very, very good.

I think Donald Trump thinks of Putin as being a strong person, and I think he thinks of himself as being a very strong person. But I don't think in any way that he thinks of the Putin government as a desirable model.
