Mike from Mother Jones sez, "For our upcoming "dark money" print package, we chartified the known galaxy of outside political spending groups by their size. As you can see, we ended up with red giants and blue dwarfs."
If Citizens United was the Big Bang of a new era of money in politics, here's the parallel universe it formed: rapidly expanding super-PACs and nebulous 501(c) groups exerting their gravitational pull on federal elections. A group's size in the chart below is based upon all known fundraising or spending since 2010…so keep an eye out for dark matter. Come back for regular updates.
