Well, he as much as admitted he was corrupt while he was "fighting" for McCain/Feingold.
Probably some good "I'm corrupt" McCain quotes available for the looking.
No doubt. But what I had in mind was suing his campaign for violations, and seeing to it that the suits got some press. Same sort of thing that he tried to do with Obama's foregoing of public financing, but in my case, I'm suggesting looking for reporting violations, violations in advertisements, etc. It costs time and money to defend against complaints and lawsuits, even if he wins.
