Wikipedia founder, Jimmy Wales, celebrated the 4th web 2.0 style by launching Wikia, a social wiki for political campaigns. From his mission statement, an open letter to the political blogosphere:

The candidates who will win elections in the future will be the candidates who build genuinely participative campaigns by generating and expanding genuine communities of engaged citizens...

Ok, I might be crazy. I founded Wikipedia, which is of course about as crazy an idea as anyone might imagine. And you know what? I was not and I still am not smart enough to figure out how to make Wikipedia work. The Wikipedians figured that out, my role has only been to listen and watch, and to guide us forward in a spirit of sincerity and love to do something useful.

So, I will frankly admit right up front: I don't know how to make politics healthier. But, I believe that you do. I believe that together we can work, this very election season, to force campaigns to use wikis and blogs to organize, discuss, manage, lead and be led by their volunteers.
