Joe Truss has posted this video on the Green Party  over at Green Change.
A thought provoking documentary created by members of the Green Party, in support of Ralph Nader, Cynthia McKinney, Rosa Clemente and Matt Gonzalez. What is the Green Party? Who are the members? What is Independent Political Action? How is it different from the Democratic and Republican Parties? What next?
