These measures are on the ballot as a result of citizen petitions, and some appear to have better chances of success than others do. > Voters in at least nine states on Tuesday will determine ambitious environmental measures, including an initiative to rein in greenhouse gas pollution in Washington that could be repeated in other states if successful as well as proposals to increase renewable energy standards in Arizona and Nevada. In four deep-red states residents will go to the polls to vote on Medicaid initiatives, a year after Maine became the first state to approve an expansion of the low-income health program via a citizen-driven ballot proposal. (Maine’s governor  has refused to implement the expansion.)
