The United States survives so long as at least one of its major parties is politically and intellectually healthy.

When it comes to trade, when it comes to standing up to countries like North Korea, when it comes to standing up to guys like Vladimir Putin, Donald Trump is not a conservative.

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

In taking care with language, we take care of ourselves.

In the Middle East there are two kinds of regimes - those that could be worse, and those that couldn't be worse.

Hillary Clinton, as awful as I find her, is a survivable event. I'm not so sure about [Donald] Trump.

I think a Donald Trump presidency sets up an Elizabeth Warren ascendancy. And it not Elizabeth Warren, someone of her ilk. And I think that's dreadful.

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.

I don't think the Republican Party, or I should say the Republican Party as the vehicle for modern American conservative ideas, survives with Donald Trump.

I have been writing about Hillary Clinton, I just actually looked this up, since 1998 when she was busy standing by when Suha Arafat was launching anti-Semitic tirades against Israel and the Jews.

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.
