30 Reasons was a 30-day email and internet campaign to encourage people to vote for Barack Obama. The goal was simple: Use design to build a logical, multi-faceted argument for Obama and make it easy to share each reason with another person.
30 graphic designers created a poster that represented a reason to vote for Obama. Every day a new poster was released and posted online. Whether it contributed to get Obama elected is not known. But the idea is great. Alike the posters.
