p>If you really want to "get money out of politics," you need to (as much as possible) get politics out of the economy. (Ideologues will always lobby, and that's fine, because it's the crony capitalism and pay-to-play aspects that are most objectionable.) Which, of course, is not what many reformers want to do. Until they do, they are basically advocating spreading sugar around their picnic blanket, and then complaining about all the ants.
Check out Laurence Lessig's speech "We the People, and the Republic we must reclaim" . The premise is that there is no way to even start getting politics out of the economy (or any other sensible legislation) until we remove money from politics.
