[Donald Trump twitts] "Lightweight Marco Rubio was working hard last night." This is true. "The problem is he's chalker and once a chalker, always a choker," I guess that's what he meant to say. He spelled choker, c-h-o-k-e-r.

What's important to do is we must deal frontally with this threat of radical Islamists, especially from ISIS. This is the most sophisticated terror group that has ever threatened the world or the United States of America.

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.

We're also optimistic about the future, but only if we do a few things.And that's a big difference in this campaign between Donald Trump's campaign and mine. And I think that's going to begin to matter a lot more now because there are less people in the race and more time to pay attention to some of that.

There's never going to be a time where the Republican Party rallies around and says you have to get out or anyone has to get out for purposes of rallying around Donald Trump.

Every generation in America has faced the same question, do we we want America to be special? Or do we just want America to be another country? The time has come again.

The children of the Reagan Revolution are ready to assume the mantle of leadership.
