The New Politics Institute offers a video interview with DailyKos founder, Markos Moulitsas, on the past and future of blogs in the political sphere. Markos, who helped found The New Politics Institute, talks in the interview about how blog communities operate within the spectrum of US politics and how political activism and 'people powered' politics have claimed a growing role in the post-modern era of political campaigning.
If you haven't yet checked out the New Politics Institute website I encourage you to do so. The site offers several videos and reports addressing the role of online campaign tools.
