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

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.

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.

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.

Donald Trump, I guess one idea here if he`s flip flopping, has he bought himself cover with his base by all the inflammatory thing he`s said over the last year? But the flip side is, all of those inflammatory things, the voters he`s trying to reach by flip flopping, are they tuned out to him because of that?

We`re seeing point to something that`s happened over the last eight years during the [Barack] Obama presidency, and that is the Democratic electorate over the last eight years has gotten a lot more liberal.

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