Chris Christie's rise in politics in New Jersey, in many ways, was built on his takedown of Charles Kushner. He got national headlines for that prosecution.

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.

To the extent anybody had heard of the [Charles] Kushner name at that point, it was a very tarnished name.

[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.

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.

Here`s what I`m curious about. For the president of Mexico, this man, Donald Trump, is, it`s probably not an understatement to say, despised by many Mexicans.

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?
