How Much Has Citizens United Changed the Political Game? - NYTimes.com
Jared Sperli stashed this in politics
not too long but an interesting look at campaign $$$
But there are alternate ways to interpret this data. The level of outside money increased 164 percent from 2004 to 2008. Then it rose 135 percent from 2008 to 2012. In other words, while the sheer amount of dollars seems considerably more ominous after Citizens United, the percentage of change from one presidential election to the next has remained pretty consistent since the passage of McCain-Feingold. And this suggests that the rising amount of outside money was probably bound to reach ever more staggering levels with or without Citizens United. The unintended consequence of McCain-Feingold was to begin a gradual migration of political might from inside the party structure to outside it.
