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.

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

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.

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.

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.

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.

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.
