In the history of humanity, there's never been a country like America.

A very good friend of mine spent a fair amount of time doing postmortems and met with a number of the senior folks on the Romney campaign and they spent, what was it, $140, $160 million on data. And this friend of mine, who is a very sharp thinker, asked a series of questions, but the most important one he asked, he said, "What decisions did you make differently because of the data?" And he's coming from the private equity world where he wants to know, OK, and the answer from virtually every single senior Romney person was "nothing."

I think President Obama is the most radical president this nation's ever seen. And in particular, I think he is a true believer in government control of the economy and of our everyday lives. In my judgment, we are facing what I consider to be the epic battle of our generation, quite literally the battle over whether we remain a free market nation.

I do think we should be focused on substance and record. If you want a candidate who opposes amnesty, who opposes citizenship for the 12 million people here illegally, I'm the only candidate in the race who opposes that.

I can tell you is all nine of the people here [on debates] would make an infinitely better commander in chief than Barack Obama or Hillary Clinton.

I think we need to be fighting for the working men and women of this country, not the moneyed New York interests.

Two-thirds of Americans think our kids will have a worse life than we did. That is a powerful indication we are on the wrong path. I think we can change that, but I'll tell you, that's what I'm going to fight to do, and the reason so many grass-roots activists poured so much into it is they believed in our country. They believed in liberty.
