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.

Hillary Clinton's record in office is dreadful. Her ideas are dreadful. They will make us less safe. So, but there is no way I'm going to vote for a guy who is just totally uninformed, un-presidential as Donald Trump is.

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.

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

Who knows better than you what it means to have a commander-in-chief who lived his entire life, who lived throughout the entire Cold War, and doesn't know what the nuclear triad is? It's absolutely astonishing. And so it's terrific to have Joe Dunford and you know, perhaps John Bolton and other people in positions of trust.

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.

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.
