The smarter congress critters, especially the ones with appropriations influence, won't grandstand for Wonderboy. When it comes time to fashion a budget and the USADA/anti-doping line item is considered, if Wonderboy's lobbyists are doing their job the USADA's budget gets smaller.
Go back to Fabiani's work. The Federal investigation evaporated and Fabiani's activities remain undocumented. That's why you pay lobbyists.
The how it gets done by a lobbyist is a discussion about USADA with a bunch of dishonest representations about what USADA are doing, and then closing with an "oh yeah, livestrong wants you to appropriate more money for awareness/bill xxyyzz." Or, if it's Demand Media, drop a line at the end about how great SOPA is or something. And then the lobbyist makes a little money rain on the congress critter's election campaign. Totally legal. Maybe you aren't from the U.S., but this is how the game is played. If you are from the U.S. you need to know how your political system works.
Hog, it's not about 'shutting down USADA.' It's about gutting their future budget, then attempting to overwhelm them with litigation so Wonderboy's team can fabricate a legal exception against weak legal representation. This is a classic business tactic in the U.S. anyway. And yes, I think that's Wonderboy playing way out of his league. Now, I think USOC would have something to say about all of this because his doping is now tainting the favorable perception of the Olympics. Once again, Wonderboy probably has inspired quite a bit of chaos/infighting, this time with USADA and USOC, perhaps all the way into the IOC.
