SEN. RAND PAUL:

Maybe not quite as bad as you would think, because young people aren't really watching the traditional. They're getting things from their friends. They're getting things passed around that are funny or humorous.

And they're not really wedded to the cable news so much. And I think it is a disservice, though, that the news, I think, has really dumbed the whole thing down, because it's been a nonstop Trump circus for months and months now. If you add up all the coverage of all the other candidates, he's getting 25 times more.

So, is it any surprise that he's leading in the polls? Which came first? Was he leading in the polls or the coverage? It's been a little bit of both. But I think it's a disservice really to the country and to getting a serious debate, because, see, I think it's important to know who's going to be in charge of the nuclear weapons.

Trump doesn't seem — in the last debate, the CNN debate, he didn't seem to understand what the nuclear triad was, that we have land missiles, sea and air. And then a week after the debate, his campaign was asked, and they said, well, yes, we knew about nuclear weapons, and our problem is we haven't been willing enough to use nuclear weapons.

And that's a pretty profound and scary thought, that we would have someone running who thinks we need to use our nuclear weapons more.
