Politicians make promises and they don't do what they said they would do: the reason why so many politicians in Washington are unhappy with me.

Any military force should be dictated by the vital national security interests of the United States. And if and when we use force, we should use overwhelming force for a clearly stated objective. And then when we're done, we should get the heck out.

I think if you're at home and you don't want Donald Trump to be the Republican nominee, then the only candidate who can beat Donald is our campaign. And so I would encourage, even if you like another candidate, stand with us if you don't want Donald to be the nominee.

I believe in the American people. It's - I believe in trusting them, I believe in empowering them, and I think, at the end of the day, the only force strong enough to change the course we're on is the grass roots across the country.

Let me say something at the outset. The questions that have been asked so far in this debate illustrate why the American people don't trust the media. This is not a cage match. And, you look at the questions - "Donald Trump, are you a comic-book villain?" "Ben Carson, can you do math?" "John Kasich, will you insult two people over here?" "Marco Rubio, why don't you resign?" "Jeb Bush, why have your numbers fallen?" How about talking about the substantive issues the people care about?

In my entire time in Washington, I treated everyone with respect, with civility.

The Democrats right now are living in an alternative universe.
