It goes back further. Sunshine laws of the 70s enable vote buying and coercion. Addressing the lobbying issue would play a big part, but ultimately the ability to apply public pressure on how representatives vote is going to provide enough leverage to control those votes. Make votes (and many committees) secret like every good election. There will still be corruption, but individual legislators will be less beholden to private interests and the party line.
