More than any other Republican presidential prospect, Sarah Palin draws white-hot journalistic loathing. She’s too red-state, too gun-toting, too religious, and too unwilling to abort a disabled “fetus.” Even so, filmmaker Steve Bannon remains deeply optimistic his forthcoming Palin documentary “The Undefeated” will sway the media to see Palin in a different light. Bannon, a former Goldman Sachs banker turned filmmaker, told National Review’s Kathryn Lopez that once he and his producing partner delved into Palin’s life story, “we decided that not just the American people but even the mainstream media were both fair and decent — that when presented with something that represented a completely different point of view they would be at least open to considering it.” The movie is not an attempt at objectivity. It’s a campaign film, a longer version of the kind Harry Thomason and Linda Bloodworth-Thomason produced for Bill Clinton. You know, “I believe…in a place called Hope.”
