Earth to Obama, McCain lobbyist-purgers: The point is not to vet the vetters who vet the vetters ad infinitum, until we have achieved Ethical Cleansing.
Reality: All the major players who know how to run campaigns and find the hidden levers are either lobbyists, friends of lobbyists, former lobbyists, or people who have benefited from lobbyists’ toil in the past. You can’t get there from here without some use of the L-Worders.
The point is to get someone in office who will start building a new system that will not rely so heavily on the big dollars from the big lobbying firms. There are all kinds of ways to reduce their influence, but the current purer-than-thou purge is a silly sideshow.
