Hey, this is a good example of genuine grassroots democracy:
ObamaTravel.org is a platform that connects volunteers who want to travel to a swing state with financial sponsors and swing state host families. It's sort of a political hybrid of craigslist and Team-in-Training – volunteers post profiles and solicit sponsorship from their family and friends. Sponsors can see their donations in action by following the activities of their volunteers.
… and let's remember that "community organizing" is pure grassroots democracy.
