Ambinder reports on a drop in registered lobbyists here, noting that

Obama has implicitly raised the cost of being an “active” lobbyist by refusing to hire any.  I have the distinct feeling this will lead to a decrease in the number of people who call themselves lobbyists, but necessarily a decrease in the amount of actual activity that resembles lobbying.  If Tom Daschle taught us anything, it’s that you can just call yourself a consultant.

“Refusing to hire any?”  Is that per the Obama campaign circa mid-2007 or Obama administration policy?
