If you haven't seen this already, it's a competition started by the Move On organisation [www.moveon.org
] to spur people into making political advertisements to get their point across. The fact that Bush has funding directly from his Government to pay for his political campaign, whereas other competitors have to rely on donations, is grossly unfair and allows for a skewed viewpoint. The purpose of this competition was to get people to make low-budget films that were high on creativity and to get them out to people where they can be shown (they are all released under GPL-Like licenses).
Some of them are brilliant, well recommended for people into film making and media issues: [www.bushin30seconds.org
