The Canadian Green Party has put their campaign proposals on a site, and is soliciting public comment in the form of ranking, as with this list of policies affecting the Business climate. Viewers can vote up or down in traditional slashdot style, with the added limitations that there is no further characterization of a vote and that all you can do is re-sort the list -- no explicit numerical distinctions are retained (though they have set up an interface to flag 'at-risk' proposals, which I take to be those modded down by more than 50% of the users.) This was reported on BoingBoing as being a wiki, which is an interesting way to do emergent policy proposals among a group (the Dean campaign was using Socialtext in this way as well), but if it's a wiki, it's not a public one. Because of the dictates of partisan politics, wikis tend not to work well in places where _everyone's_ motives are suspect, meaning that the wikification of policy is mostly among insiders. The Green Party site looks like it embodies this form -- you can suggest new amended policies only through email, where they go through a vetting step before reaching the site (if they ever do), while everyone has access to the voting interface.
