Comedian Stephen Colbert no longer just plays a political pundit on TV; he's also running for President - though only on the South Carolina primary ballot. And he's already polling over 2% among Democrats. Despite his claim that Doritos is the main sponsor of his campaign coverage, I don't think that his campaign would be possible without the internet.
The Colbert '08 site was set up to mobilize his voters as soon as his candidacy was announced. The Colbert Report website, No Fact Zone, has a collection of blog posts that cover his Presidential run, as well as a trove of links to articles and other media about this event.
The internet also allows his fans to discuss his Presidential run and express their opinions. Fans all across the country are able to share information with each other about the rules and procedures involved with South Carolina primaries. There are also debates on blog communities over just how far he will, or should, take his Presidential campaign.
