With President Trump's nomination of federal judge Brett Kavanaugh, the Supreme Court will likely be locked up by the political right for a generation. This is in large part thanks to a historic decision made in 2010 by the court’s then-shakier conservative majority: the Citizens United ruling, which fundamentally reshaped the political landscape of the United States by unleashing floods of political spending, particularly in the form of untraceable "dark money."

For the state of Montana, the post-Citizens United world has brought back old memories: over a century ago, copper kings like William A. Clark used their vast wealth to control the state and buy up political power. In 1912, the state responded by passing one of the first campaign finance laws in the nation, banning corporate political spending entirely. That law was struck down by the Supreme Court in 2012, but Montanans have continued to push back against corporate political spending using other means.

A new documentary, Dark Money, uses Montana as a microcosm to explain the reality of campaign finance in the United States today. Bob speaks with director Kimberly Reed about the documentary and why she's hopeful that, despite the unbalanced playing field, positive change is possible.
