I would argue that there's been a backlash this year [2016]. They [the Kochs] pushed the [Republican] party too far right. The other thing that the backlash is against is the sense that politicians have been bought and sold.

The Kochtopus is the nickname that people who've worked for the Kochs came up with because there's so many tentacles and it likes the shadows. I really feel the first step is to provide the information.

David and Charles Koch are pretty much as far right as you can get on the ideological spectrum without falling off. They are far right libertarians, very anti-government, very pro-business, very anti-tax, anti-regulatory, in favour of free markets ruling the day.

It's quite amazingly radical, what their [the Kochs] vision of America would be.

[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.

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.

The book that I wrote is called Dark Money, and it's about secret spending that is very hard to follow. [George] Soros's whole thing is about government transparency, so he spends very much in the open, and the same with [Tom] Steyer.
