Yes, I would love for my representatives to cater to the special interest known as me. They won't. They won't even if I am Warren Buffet. Really, they won't. They are probably more likely to listen to Warren Buffet than me because of his accomplishments but I doubt Warren Buffet has ever asked for something because it would benefit only him. Business men generally lobby for things on the basis that it will benefit everyone like him and all those he now employs or those he will be able employee after getting whatever he is after.
By the way, which special interests should Congress not listen to? NRA, Brady Campaign, Sierra Club, ranchers, Chamber of Congress, AFL-CIO, UAW, Chrysler, Ford, AMA, Trial Lawyers, NAACP, Humane Society, PETA, SPLC, Freedom From Religion, Southern Baptist Congress, insurance companies? The problem with special interests is that everyone generally wants the "bad" ones banned and the "good" ones to have more access and everyone has differing definitions of good and bad. I'm all for banning the access of the bad special interests as long as I get to define "bad"?
