So on NPR yesterday they mentioned a (proposed?) Congressional inquiry into the Abramoff garbage, and speculated that Congress was going to crack down on donations by lobbyists.
So let me get this straight: Congress steals a bunch of our money at gunpoint. Some groups want to have less of their money stolen, or they want a piece of the action, and so they hire lobbyists to give bribes and other goodies to the politicians. To deal with the public's outrage over this, Congress decides to use men (and women) with guns to punish people who give them bribes in ways other than the prescribed manner.
