His version of "bottom-up" is heavily funding astroturf campaigns as well as more populist groups through which he can control what they do.
Mr. Koch and his late brother David seeded the political landscape with conservative and libertarian ideas, then built an infrastructure to nurture them. Koch-aligned ventures fund more than 1,000 faculty members at more than 200 universities, helped bankroll think tanks such as the Cato Institute and the American Enterprise Institute, and supported the American Legislative Exchange Council (a nonpartisan organization of similarly minded state legislators) to write bills that were introduced and championed by Republican state lawmakers across the country.
You know what would really decentralise the country and create a bottom-up utopia? If no single entity had the resources the Kochs has. But in the world of the Kochs privately funded authoritarianism does not count.
Can it get any more cynical than this?
