Yep, that's what they said about Goebbels' movies, too.
Powerful is not the same as truthful.
When I see a video made in the manner in which that one is made, I automatically assume it's false — that the author, if he had the facts, would not need to fill his video with shots of broken-down victims, shuttered factories, and obviously out of context quotes from the target. But I am not the sheeple.
True or not, if the video keeps Mittens from being the nominee, that will be a Good Thing.
