I recently blogged about this, particularly on how Barack Obama has successfully leveraged social media for his campaign, and although it's not an in-depth analysis of how social media is changing politics (nor I believe this article), it's basically to point out how social media can be a game changer in politics today. I guess this will all the more be verified soon after the elections.
My first comment would have been more accurate had I used the word "potential" in talking of social networking's impact on the 2008 election and beyond. I believe that we will see a filtering down of this phenomenon in the future to encompass all levels of campaigning. Our goal, specifically, is to provide a place for local, state, and national politicians, citizens, and political advocacy groups to come together in one central forum to exchange ideas, interests, and information on all things political, while providing a template for the campaigns themselves to have an online suite of campaign management tools at their disposal, making it easier for them to take advantage of this medium and its networks. I don't think we can ignore the fact that the Obama campaign has shown us the power of the internet in rallying a grassroots support base. As far as I know, there has not been an election in my lifetime where the machine backed candidate did not win their parties' nomination. That's exactly what Obama has done and he did it using the internet.
