Supporters of marijuana legalization say part of their focus on Maine is schematic — the ease of Maine's citizen-led public ballot initiative process makes it a more viable target than states where laws can only be changed through complicated state legislative battles. Maine supporters are already crafting the ballot initiative for the 2016 election cycle, according to David Boyer, a Falmouth resident and political director for the Washington-based Marijuana Policy Project. Maine's ballot initiative will face significant opposition from some public and law enforcement officials, some of whom campaigned against legalization in its cities. Roy McKinney, director of the Maine Drug Enforcement Agency, said the legalization vote in South Portland — where voters approved a measure to allow people age 21 and older to possess an ounce of marijuana — doesn't supersede state law.
