Obama's America: 2016 fell from number nine to number 13 in gross ticket sales last week. The documentary was in 141 fewer theaters for a total of 1,876. Gross ticket sales were down by 38.6%. This movie has earned a respectable $30 million in ten weeks which is pretty darn good for a political documentary.
By way of comparison, The Expendables II has earned $80 million in five weeks and Michael Moore's Farenheit 9/11 set the all time record for a political documentary with $220 million in gross ticket sales. http://boxofficemojo.com/weekend/chart/
