The front line with ISIS isn't just in Iraq and Syria, it's in Kennedy Airport and the Rio Grande. Border security is national security.

I'm not going to impugn anyone's integrity. I'm not going to attack their character. And, in fact, I will happily praise both Donald Trump and Marco Rubio as men who I admire, as people who I'm not going to go personal with them.

As president, I wouldn't be making the day-to-day combat decisions. The job of the commander-in-chief is to lay the objective out and then you rely upon the generals and admirals and commanders to give you their expert advice on the tools needed to carry out that objective.

A friend of mine, a Hispanic entrepreneur asked me a question sometime ago, he said, 'When is the last time you saw a Hispanic panhandler?' I think it's a great question. I'll tell you, in my life I've never once have seen a Hispanic panhandler, because in our community, it would be viewed as shameful to be out on the street begging.

A very good friend of mine spent a fair amount of time doing postmortems and met with a number of the senior folks on the Romney campaign and they spent, what was it, $140, $160 million on data. And this friend of mine, who is a very sharp thinker, asked a series of questions, but the most important one he asked, he said, "What decisions did you make differently because of the data?" And he's coming from the private equity world where he wants to know, OK, and the answer from virtually every single senior Romney person was "nothing."
