Ballot Box Zoning
The Initiative and Referendum Institute analyzes and promotes the initiative and referendum processes. Its mission is to "research and develop clear analysis of the initiative process and its use; to inform and educate the public about the process and its effects on the political, fiscal and social fabric of our society; and to promote effective leadership in litigation - defending the initiative process and the right of citizens to reform their government from career legislators who want to take it away." Information on ballot measures currently under consideration is available as well.
Americans for the Environment also has a ballot initiative page which takes a much dimmer view of initiatives, characterizing initiatives as a right-wing method, "to advance their economically regressive, environmentally destructive, often intolerant political agenda."
