Here`s an interesting twist, though, President Pena Nieto later tweeting that he told [Donald] Trump in their private meeting that Mexico will not pay for the proposed border wall, Trump saying, though, in that press conference that it didn`t come up.

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

The perception that Donald Trump has softened on immigration or is about to soften on immigration has some on the right concerned that he could lose support among his most loyal base of supporters, though he`d been drawn to his hard-line positions on immigration early in the campaign.

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?

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.

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?

I don`t know how it would have gone, but I do know this - Mitt Romney was looking at running and the reason he decided not to run was because he decided that someone was unbeatable. That someone was Jeb Bush.
