As is widely known at this post-Citizens United stage of democracy in the United States, big, untraceable money plays a major role in our elections and the formation of government policy on local, county, state, and national levels. Kimberly Reed’s incisive documentary tracks several varieties of this dynamic, focused on politics in Montana, which has a long and sordid history of power abuse. Following independent journalist John S. Adams as he doggedly tracks a case of financial corruption in the Montana state senate, but also searching deeper into the underlying structures at play, Dark Money is a riveting journey into an area of public life that we are only starting to fully understand. “Potent! A rather harrowing portrait of democracy under threat, even if ultimately there is hope.”—Dennis Harvey, Variety. “As heartening a political story as you are going to get these days.”—Kenneth Turan, Los Angeles Times.
