Mother Jones just posted a new interactive map that lets you explore the dark-money universe of the 2012 election. They theorize that if “Citizens United is the big bang of a new era of money in politics,” then this is the universe it created. The size of the planets — super PACs and 501(c) groups — corresponds to the total money raised so far.
Best part? The data is live and updated on a weekly basis. Visit Mother Jones to explore the chart.
