Last month, the Koch Brothers ramped up their efforts to take control of the right-libertarian Cato Institute. Cato has long been a beacon of independent thought, not tied to one political party or another. The Kochs are apparently trying to push the think tank in a more blatantly pro-corporate direction.

Last week, we talked to Rep. Jared Polis (D-CO) about why he opposes this Koch takeover. Polis told us that it is “very scary” because Cato’s “intellectual integrity” is being challenged by the Kochs. Watch our interview:
