Obamacare is the nation's biggest job killer and stands in the way of our country's economic growth and prosperity. It should be defunded and repealed. President Obama should hear the pleas from the untold number of Americans who are losing their jobs, wages, and healthcare plans, and Congress should act immediately to stop Obamacare from inflicting any more damage on the country on our hard-working citizens.

Everyone seems to have internalized the fact that you can say anything you want at a televised debate, and only a tiny fraction of the audience will ever see a fact-check. So why not claim the moon is square?

Donald Trump threatened to file a defamation suit against me for running a TV ad that consisted only entirely of his own words on national television. Now, that's really a remarkable theory, that it is defamation to show people what he said on national TV. I think the voters are smarter than that.

The left keeps talking about impeachment. I mean, they were talking about impeachment before Donald Trump's inauguration in 2017. And, you know, I think impeaching Obama in January probably would have been a mistake.

Listen, Bernie Sanders talks about how Washington is corrupt, both parties are in bed with the lobbyists and special interests. I think he's exactly right.

Washington D.C. politics is like Hollywood for ugly people.

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?
