Republic, Lost[0] is a really good read on this (even if it is by Lessig himself). He lays out how he would see the process working, I believe at the Presidential level. The basic idea is running on a platform that promises change as well as a commitment to step down once said change is accomplished. With the amount of money already wrapped up in politics (especially between two large parties), it strikes me as a tough sales pitch for either party's old guard.

To your point about there not being enough money in politics: I'd agree with you if money existed in a vacuum for its own sake. The question should arguably be is there enough/too much purchasable influence in politics.
