According to Office Mojo 2016, Obama's America ranked 9th over the Labor Day holiday weekend. While this was down from 7th last weekend the film expanded its release by 656 to 1,747 theater. What has to be impressive to theater owners is that 2016, Obama's America ranked third this weekend in that all important number of revenue per theater at $3,198. Only two new released films earned more per theater, The Possession at $6,286 per 2816 theaters and Lawless at $3,463 per 2,888 theaters.
If a documentary by a left wing media darling like Michael Moore were performing this well at the box office there would be far more major news stories about the film and how well it is doing at the box office.
