[Donald] Trump met with Mexican president Enrique Pena Nieto, who has in the past compared Trump`s rhetoric to that of Adolf Hitler and Benito Mussolini.

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.

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?

Bernie Sanders is usually speaking to the converted. He fires them up. It`s a completely different style of campaigning that he`s allergic to.

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.

Immigration has been [Donald] Trump`s signature issue throughout his entire presidential campaign, and his supporters love him for it.

The specifics of the platform, I don`t think, are necessarily going to be written by Bernie Sanders, but the themes of the platform are going to be written by Bernie Sanders.
