If you look at the Bernie Sanders of today and you look at the Bernie Sanders of a year ago [2015], when this started, he`s come a long way in terms of.This was a guy at the start of the campaign who had contempt for any personal questions.

Hillary Clinton's weakest group, though, is people under 30, the young.

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.

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.

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

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?
