I started as a community organizer. Every one of my campaigns was premised on getting new people involved. And if there's a theme in my public career it's that if ordinary people get involved then good things happen. So I want to see the Democratic Party move in that direction. And what that means is that we aren't just micro-targeting to eke out presidential victories; it means that we're showing up in places where right now we're not winning a lot.
