The Koch bothers essentially own an entire political party. While their political contributions and influence has not resulted in any major changes in policy and legislation in recent years, they have successfully prevented a popular (at time of election) democratic president from making any major impact on policy. After the 2012 elections, a lot of press was written about how much money was spent on Republican elections and how little success resulted. But if you look at the House of Representatives, despite the fact that overall, more votes were democratic, the Republicans still walked away with a clear majority of seats thanks to redistricting. And of course, the majority in the house allows Republicans to obstruct just about anything. If the Koch brothers weren't getting a return on their political contributions, I highly doubt they would continue to do so. After the recession there was a big push for wall st regulation, higher taxes on the 1%, and increases in welfare program funding, and yet nothing meaningful came from it despite popular support. My guess is the Koch brothers consider that a success.
