I couldn't describe the mechanics of the thing for you but my point was that it was a good idea. Would it take much more than a few changes to accounting law?
Anyway my real point was that not all of the voices will be coming from inside his head and that seemed encouraging.
Banning lobbyists seems a stupid idea. The personal access of top CEOs and the megarich would not go away - some of them are in the cabinet, after all. But access becomes harder for non-profits, advocacy groups, unions etc. What's this supposed to achieve?
