Donald Trump has the benefit of the fact that he's dominated media coverage, I mean, literally dominated media coverage because of the outrageous things he says and so forth. That's going to end here. There's going to be real fight now for the heart and soul of the Republican Party and the conservative movement. And it is not - I will do whatever it takes to prevent it from being taken over by a con artist.

I mean, on virtually every major issue before this country that is the natural purview of the federal government, it's important to have some specificity about what you're going to do if you want to be the president. And so I agree that, up until this point, it hasn't been a huge factor.

I've always said that I'm open to changes in the relations between Cuba and the U.S., but that Cuba must make changes also.

The erosion of equal opportunity is among the greatest threats to our exceptionalism as a nation. But it also provides us with an exciting and historic opportunity: to help more people than ever achieve the American Dream.

Even if we didn't have a single person in the USA in violation of immigration laws, we'd still have to do immigration reform, because our legal immigration system is broken. It's not good for anybody.

Anger alone is not going to be enough. You deserve a nominee who tells you exactly, "Here's what we're going to do," and outlines that. So you know what you're getting. So there's some level of accountability here. So my campaign is about this. We are very realistic about our challenges right now in this country.

Donald Trump is never going to be the nominee. So, I'm not worried about a hypothetical that's never going to happen.
