Howard Dean, the favorite of many in the last Democratic Primary, was officially removed from the pool of potential presidential candidates when he became the chair of the Democratic National Committee.
Deans position came to him not through politicking himself through the traditions of congress nor by appeasing lobbyists. His grassroots support was so broad and firm that the democratic leaders did not see it possible to find a more profitable man for the job. The accepted him as chairman of the committee because accepting him sends a message to his supporters that they (and their money) is also accepted.
This is what many have been waiting for - a nod from politicians that what they’ve worked so hard for through grassroots campaigning can hold some sway in the capitol.
