Short, viral video impacts 2008 presidential election

This 2008 video short "McCain's Mansions" from Robert Greenwald's Brave New Films (with more than 600,000 views) percolated up through the media food chain into the mainstream, where it exploded.  It impacted the campaign, as shown by this self-promotional video, "The Making of McCain's Mansions."

Four years earlier, Greenwald's "Outfoxed" -- a low-budget documentary -- was reviewed by the New York Times movie critic at a "house party" held at a Brooklyn bar.
