It's called Silver city and here is a snippet of what it is about (if you don't know already)
With Silver City, writer-director-editor John Sayles has whipped up a pastiche of Chinatown and the deeply sarcastic ensemble satires of Robert Altman (Tanner '88). Tracking the corrupt back-door politics of the fictional Pilager family, Sayles has his way with both George Bushes. Michael Murphy (Altman's "Tanner") plays Senator Jud Pilager, now coaching his son Dickie (Chris Cooper) in a first-time bid for public office. Dickie wants to be governor of Colorado, but first he must disassociate himself from a developing scandal. The family name implies that the Pilagers are buccaneers; when bodies begin to float to the surface during photo ops, Dickie begins to look more and more like what he is: a toxic leader.
Cooper's English-mangling version of George W. is a certified hoot, but the election is no laughing matter.
