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.

We are waiting for Donald Trump`s big immigration speech. There are lots of unanswered questions that remain about where exactly Trump stands on deportation forces, on what to do with the millions of immigrants who are here illegally now, and where he stands on the question of birthright citizenship.

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.

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

On the campaign trail, [Donald] Trump has threatened a trade war and repeatedly said that Mexico will pay for a wall on the Southern border.

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.

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?
