The greatest disaster of all was after all the difficulties and loss of life and expenditures, President [Barak] Obama walked away, in 2011, and it is a disaster. And now we've got half of Iraq under the ISIS control and terrorists, and Iran has moved in because we weren't there, and they've taken more influence. Just a few thousand troops, in my opinion, would have avoided that.

In seven years, we'll have the highest percentage of Americans non-native born since the founding of the republic. And some people think, "Well, we've always had these numbers." But it's not so. This is very unusual. It's a radical change. And in fact, when the numbers reached about this high in 1924, the president and Congress changed the policy, and it slowed down immigration significantly. And we then assimilated through the 1965 and created really the solid middle class of America, with assimilated immigrants, and it was good for America.

[Mitt] Romney didn't get beyond the numbers. He couldn't get 50 percent. Romney didn't - Romney got killed by the under-$50,000-a-year income voter. He just got killed in that.

I believe that President [George W.] Bush was correct. I thought that Iraq had weapons of mass destruction, and I supported him steadfastly, and once we committed we should see it through.
