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."

As Donald Trump continues to dominate the 2016 field, the Republican establishment's low-grade anxiety is becoming an all-out panic

Like one of any minority, I have experienced prejudice.

We have to be concerned about the gun killing that people who are Americans, who are Irish, and who are English, who are all around the country.

We build buildings based on the false assumption that women go to mosques half as much as they actually do. In fact, the US is the only country in the world where women and men report that they attend the mosque in equal numbers, but our institutions aren't representing this reality.

What have we heard from Republican voters? They want somebody that's new, they want somebody that's fresh. They don't want an establishment.

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.
