I think most politicians really want to get free of special interest money and the resulting commitments to those special interests.
The only way that can happen is to turn over fund raising to many thousands of supporters, almost certainly connected through the Net. I think that can liberate a candidate from a few well-funded groups.
I think that's why it's important that Howard Dean turned down public financing. People who're a lot smarter than me have commented that it's a smart strategy, and that feels right.
However, it's time that our representatives got back on track, and need to worry less about raising money for the next election. This is a push in the right direction.
