Mitt Romney, Jeb Bush, Chris Christie, sort of the three big hitters on the Republican side.

There was a change in tone in terms of the [Donald] Trump who showed up in Mexico City for this press conference.

Looking to Donald Trump`s immigration speech can he hang onto his base if he softens his stance on the issue that got him this far?

I think three weaknesses have emerged for Hillary Clinton in early states.One is young voters. Another is political independents. He`s winning with independents who show up. But the other one - this is the inverse of what we saw in `08 - working-class white voters. In 2008, they stuck with her all the way.

Probably not a surprise that, among the people of Mexico, just 4 percent say that they have a positive opinion of [Donald] Trump. Seventy-five percent say they have a negative opinion.

He [Donald Trump] found that sweet spot in the Republican Party, just politically, where you had the rest of the party saying it`s just impractical. You can`t deport 11 million people. You can`t round them up and deport them, and his position was basically, hey, Republican voters. Don`t listen them, you can and I will.

We played all that rhetoric, all of the thing - the provocative inflammatory things [Donald Trump] said over the last year, does that all add up to buying him enough wiggle room with his base that he can get out and change his position like that?
