The question, of course, is will these films make a difference? Films of 2004 such as "Fahrenheit 9/11" and "Bush's Brain" had lots of viewers, but Bush was re-elected. Still, with the Internet playing a role in people's lives that grows by the nanosecond, and presidential elections being won by fewer than a thousand votes in one state, a few hundred thousand hits on YouTube could make a difference, analysts and filmmakers on both sides of the aisle speculate. If not, the films and spots will generate talk on radio and cable TV.
And in an election year, anything can happen. If you had told Robert Greenwald a year ago that his shorts would pass 22 million total views, he told ABC News, "I would have said, 'You're out of your mind.'"
