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

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.

Rush Limbaugh is saying he never took Trump seriously in the first place.

This is a terrible year [2015] in a lot of ways. You have Paris. You have San Bernardino. But there was, if you remember the summer, there was that attempted terror attack on the train in France. There were two U.S. Marines, there`s one other guy. They were three guys who got up and who stopped that attack. Nobody died. They are heroes and they are my people of the year, three of them.

When Donald Trump had all of his opponents, when he had critics in his party saying what you`re calling for in terms of deportation of all 11 million is not practical, it`s not plausible, some were saying it is not moral, why wouldn`t he make argument then?

Like the kind of voter who has been turned off to [Donald] Trump, who would normally vote Republican in an election like this, that`s who we`re talking about, can they get past - even if he comes to a position that`s more agreeable for them, a tone that`s more agreeable, can they get past the last year?

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.
