Can't attack Hillary? Attack Bill!

Well, this idea is incredibly appealing:

it's a McCain-Feingold idea. George Bush is not a candidate for any federal office. This means that "Americans United for Change" can spend infinite money trashing him, and they don't even have to report their donors to the FEC. What's more, there is inevitably going to be a certain, erm, latitude concerning what constitutes criticism of Bush and what constitutes criticism of Republican policies in general...In spite of the way former President Clinton is comporting himself, Bill Clinton is not a candidate for any federal office...
