Why didn't those Hollywood lefties pick "2016: Obama's America" for the documentary Oscars?

Here's some ripe PR. Dinesh D'Souza put out the bait and Slate took it:

A total of 126 documentaries were eligible for an Academy Award this year, and a selection committee recently narrowed those down to 15 hopefuls for five nominations. Dozens were snubbed, but the producers of 2016: Obama's America say their film's exclusion is evidence of something more sinister.

The anti-Obama film directed by Dinesh D'Souza was roundly panned by critics, though it rode word of mouth to a $33 million gross. D'Souza said the film's success would have resulted in a nomination if it weren't for Hollywood's bias. "Liberal political ideology, not excellence, is the true standard of what receives awards," he said.

Obviously, there's no reason why D'Souza's movie — even if it was popular — should be a finalist instead of those other movies — which we know little or nothing about, but which the selection committee supposedly watched and judged according to a set of principles about what makes a movie Oscar-worthy. Big box office is never the key to winning an Oscar, and in the documentary category, there are some traditional standards that skew toward more neutral, historical/scientific presentations.

I'm sure D'Souza knows all this. It was savvy of him to leverage the occasion to get attention for his film, and I suspect Slate knows that. Slate will get attention for debunking D'Souza, even as it give him the publicity he wants. Everybody wins.

ADDED: You can, of course, purchase the movie, but if I were recommending documentaries that weren't nominated for Oscars, I'd have plenty of others ahead of that. ""Grey Gardens" and "Fast, Cheap & Out of Control" to begin with.
