I think when you're running for president, especially someone that's never held elected office, there's one set of things that you may view the world through - a lens that you may view the world through. Then, you get elected and you get good people. And those good people bring you the facts. And they bring you, "Here's what's going on. Here are our options. Here's what happens if you do this. Here's what happens when you do that." And that reality begins to assert itself. And you have to react to that. You're now the president. You're no longer a candidate.

We live in a society obsessed with public opinion. But leadership has never been about popularity.

We are getting thousands and thousands of professionals, very highly-trained people, from Puerto Rico who are now living in Florida, and who have obviously contributed a lot to this state, but the island is losing that population.

The air strikes are important [to fight ISIS], but we need to have an air force capable of it. And because of the budget cuts we are facing in this country, we are going to be left with the oldest and the smallest Air Force we have ever had. We have to reverse those cuts, in addition to the cuts to our Navy and in addition to the cuts to our Army, as well.

I don't really like labels in politics, but I will gladly accept the label of conservatism.

I feel bad for the kids that are in school right now and the young people all across America who don't realize that the grownups who are supposed to be running this country are the verge of leaving them as the first generation of Americans worse off than the generation before.

If Donald Trump is our nominee, it could be the end of the Republican Party. It will split us and splinter us in a way that we may never be able to recover. And the Democrats will be joyful about it. It's not going to happen.
