What, exactly, is "this corruption"? It's a fact that it takes money to run for public office, and after the McCain-Feingold law, there are only a few places to get it - Indian tribes, Unions, and a few other special interest groups. Only the independently wealthy can run without taking money from the people who can give it.
Is a Congress full of billionaires better than what we have now?
This corruption is all the life long "professional" representatives who drive around in limos, who order the IRS to investigate enemies, who travel on first class junkets to exotic places, who are wined and dined and feted to the point that they think they're bullet proof, they think their alliances are with fat cat lobbyists and they treat the electorate like we're all brain dead.
I think the most valuable benefit this investigation could possibly uncover, would be to nail 100% of those coiffed, puffed up, elitists who think they're above the rest of us!
