I think a Donald Trump presidency raises a new kind of version of conservatism which more closely resembles a kind of Father Coughlin, America first populism and nativism and isolationism, than the confident, modern, cosmopolitan, thoughtful, engaged conservatism of Ronald Reagan and Paul Ryan.

If, in 2008, I could have not been in equities, I wouldn't have been in equities. If I could have not bet on the Seahawks in the Super Bowl, I wouldn't have bet on the Seahawks. Life and statesmanship are not lived with the benefit of hindsight.

The dismissal of any of these people would send a useful signal to U.S. allies that the president has the nerve - and self-awareness - to make a change.

The only person who counts in the administration is the president of the United States.

I have a very, very hard time voting for Mrs. [Hillary] Clinton.

What is absolutely clear is that if Trump is the nominee, Republicans cannot win. Maybe they can't win with Rubio or Cruz or Kasich. We don't know. But what is absolutely certain is that with Hillary Clinton locking up the Democratic base, she is going to win unless she has a strong contender who is going to be able to pull - not only bring the entire Republican Party on the side, but win moderates. Donald Trump cannot do that.

When George W. Bush decided to save the American position in Iraq by going against the advice of all of his wise men, of Jim Baker and the whole Iraq Study Group, and 90% of his administration, that was George W. Bush's decision. So we have to bear in mind that this isn't an administration we're electing. It's a person that we are electing.
