I have no idea who made this, but it is an extensive work. See http://www.natbatesformayormovie.com. It is titled Nat Bates for Mayor, but it’s about the entire election. The trailer is at https://www.youtube.com/watch?v=U2Crtuv1uXs.
The Facebook page says, “A tale of race, corporate influence and cheese grits. Nat Bates For Mayor tells the story of the 2014 mayor’s race in Richmond, Calif.,” but has no other information.
