A new initiative to put a constitutional amendment on the 2014 ballot was announced this week. It is somewhat similar to the CA process and the summary of the proposal with a link to the draft text is here.
The coalition is looking for comments before finalizing the language for the petitions. I know there are plenty of posters here who could bring some useful comments forward. I'd be happy to see that comments on the draft get to the coalition.
The language is way too vague for me. Also, I am down on the California system. I didn't like the way the auditors picked commission panelist finalists, and then the panelists were gamed, so the final map had some highly questionable elements. I prefer a more automated system to pick map candidates, and then let the pros dicker over them, using a strike mechanism, until the available map choices are reduced to one.
