A new online video released yesterday by liberal online behemoth MoveOn.org has hit a nerve. Starring comedian Will Ferrell and a host of A-list Hollywood actors, the video has already been 1.5 million times in less than 24 hours. Ilyse Hogue, the group's director of political advocacy and communication, tells me that it is "by far our best performing [video] through social networks." She reports that nearly 250,000 of those views have come from people clicking through links that supporters of MoveOn have placed on their Facebook pages, and another 36,000 or so from Twitter referrers. Not bad. [More analysis after the jump.]
