In Tuesday’s press conference, President Obama got it right: The flood of big money into our elections has enabled more extreme politics to influence decisionmaking—and that leads to impasses like the current government shutdown. The Supreme Court’s 2010 Citizens United decision is one big reason for our money-soaked elections. Here’s what the President said today:I continue to believe that Citizens United contributed to some of the problems we’re having in Washington right now. You have some ideological extremists who have a big bankroll, and they can entirely skew our politics. Under Citizens United, anyone—including giant corporations—can contribute as much as they want to so-called “independent” organizations, like Karl Rove’s Crossroads GPS.
