Some people think [Ted] Cruz is just as bad of an electoral nightmare down the ballot as [Donald] Trump.

Because people were attracted to him because he was not elected to an office. He was not a politician. And like you said before, he was a person that people say "Wow! He has the idea!" But the more and more you listen to Donald Trump, the more you have the sense that he is not the person that's going to run the country. And I have strong views.

I don't think there's any clever way for the establishment to take Donald Trump down. It's very simple. Another candidate is going to have to find a way either to out-maneuver him, or to just frankly beat him in the argument.

If no one can do that, yeah, Donald Trump better man the lifeboats, because there's some significant chance he'll win the nomination.

Republicans advising candidates to "grab onto the best elements of [his] anti-Washington populist agenda," but warning that Trump is a "misguided missile," "subject to farcical fits" and candidates should avoid getting drawn into "every Trump dust-up," but should quickly condemn some of his comments, including "wacky things about women."
