Florida's proposed Amendment 2 to legalize medical marijuana has drawn two major groups of campaign donors. United for Care, the amendment sponsor, has attracted thousands of supporters, who, aside from leader John Morgan, most frequently give small amounts, many below $100. The Drug Free Florida Committee, the main organized opposition, pulls in bigger donations on average, but from far fewer people. The circles represent donations of at least $5,000 to either side; smaller contributions are not represented in the graphic, though they are included in the totals. You can see details by hovering over any circle. The chart will be updated weekly as the campaign progresses.
