There's been a 40-year effort on the far right to build up think tanks, academic programs, advocacy groups, to push a particular ideology. That's really where the impact is that people don't see.

The world's a small place and people are watching; and, you know, somebody disappears, the family knows and their colleagues know, and so eventually, these things do get out.

The Kochs have been activists since the 1970s. You can go back and look at the platform of the Libertarian Party in 1980 and see what they really believe in. They wanted to abolish huge swaths of the U.S. government, including the Internal Revenue Service. They want to get rid of Social Security. They'd like to get rid of Medicare. They'd like to abolish the Environmental Protection Agency, which directly affects their business.

And to me, it was interesting, some of the people I had interviewed who knew the insides to this program said that they also, to create anxiety and upset in the soldiers, they take Bibles and they trash them.

If you have an informed electorate, it makes great choices.

There's not as much big money on the left, but you've got George Soros, who has the Open Society Institute. He's pushing liberal policies.

[Donald] Trump comes along and is singing a different song. He says, "I don't need your money; I'm rich enough on my own to run." And he says, "I think we need these programs." And, lo and behold, a lot of Republican voters liked what he said.
