Filmmaker Kimberly Reed grew up in Montana with little anticipation her home state would be ground zero for a massive fight over money in politics. But her new documentary, “Dark Money,” tells a tale worthy of any Western, as lawmakers on both sides of the aisle fight for their own prerogatives in the face of out-of-state interests gunning for them.

With the nomination of Brett Kavanaugh to the Supreme Court, the high court’s role as the ultimate referee over money’s role in politics is back in focus. Reed and Campaign Legal Center founder Trevor Potter and CQ Roll Call campaign finance reporter Kate Ackley discussed the film, money in politics and the campaign landscape on this week’s Political Theater Podcast.
