Corporations have already owned the politicians; it will be less secretive now and more blatant but not too much will change. If you think you had freedom of choice before, you are sorely mistaken. The companies own this country and it's been that way for a while.
Goldman Sachs, Exxon, Shell, Halliburton, KBR, Lockheed Martin, etc. are all buddy-buddy with the politicians and many of their executives were former politicians themselves and vice versa (see revolving door politics and the military industrial complex). It's a rigged system.
