This website (http://www.beyonddelay.org/) is pretty good and informative.

They'd have a much better time, and less work, documenting the few that are not corrupt.

Which is the reason lobbyists should be banned from politics alltogether.

That's a spiffy site and one I intend to browse more thoroughly later. In recent days Santorum has really upped his mud slinging TV ad campaign against his opponent Bob Casey in PA's Senate run. I can't stand Santorum and I will definitely not vote for him in November :)
