Terry Gross asks biographer Daniel Schuman why the Koch Brothers need so many different political organizations, instead of just one

On Fresh Air's May 21st show, How the Koch Brothers Remade America's Political Landscape, Terry Gross interviewed the author of Wichita: How the Koch Brothers Became America's Most Powerful and Private Dynasty, Daniel Schulman, who took great pains to explain what the Kochs are not:

     The Kochs have always had an uneasy relationship with the Republican Party, or they traditionally did, because their politics aren't exactly Republican, they're very much more libertarian, and there's only a narrow subset of issues on which they actually agree with Republicans...For instance, they're generally anti-war. They're civil libertarians; they are not social conservatives in any sense of the word. David Koch has said he's pro-gay marriage. You wouldn't see these guys advocating against reproductive rights.
     ....Across the board, the Kochs are anti-regulation... They view climate change and any regulation surrounding it as a major threat to their business model, which is a lot having to do with oil and petrochemicals. They have certainly funded an array of groups that have tried to create doubt about the very existence of it...
