If there is one lesson I am learning from the Dean campaign it is that you can
have an impact on the political process without necessarily coming out on top when the votes are counted. Democrats in recent years have become so focused on the big 'W' wins that they have lost sight of the value little 'w' wins.
Even if he only represent 20% of the Democrats, Howard Dean can have and has had a powerful influence on the direction of the party. Whoever the eventual nominee is, they will need that 20% to make it across the finish line first next Fall. By staying in the race Dean can keep the pressure on the rest of the party to remain honest.
It's coalition politics. Something that hasn't been practiced in Democratic circles in quite a while.
