There’s been a lot of talk in the last few weeks and months about John McCain’s ties to lobbyists. So here at TPMmuckraker, we decided to do a little digging to officially catalog the possibilities. What we came up with, we fondly call “John McCain’s Lobbyist Universe,” a working guide to the presidential hopeful’s connections. Click on each of the familiar faces to get a synopsis of their role in the campaign and their lobbyist ties. We expect to be growing and expanding this chart as more facts come in, and as always we welcome any tips or knowledge that you, our readers, have to offer.
