Apparently, calling a lobbyist something else, or getting them in via the back door along with high paying guests is just OK with the Obama administration who for-swore lobbyists, at least directly.
The times article points out, for example, that Bush has visited the white house 9 times. Not George W. but Antoinette C. Bush, a high profile Washington attorney who has represented the likes of Viacom. The Bushes have also, coincidentally, donated heavily to the Obama reelection cause.
