the democratic party is oldest continuous running political party in the world.
i think, while in theory, it could be shaped by the efforts of grassroots organization, it doesn’t exist just to address particular issues or constituencies – but also to maintain its own existence. ( that can be a good thing: like when it mophed from the party supporting slavery and racial segregation to the party it is today. but, it took time. )
the primary ( no pun, i swear ) issue is the dnc. it shapes the party’s platform, fundraising, favored candidates, etc. the dnc does have some 400 elected members, but to be eligible you’d have to work within the framework of its rules and charter. you’re not going to see a radical takeover by some concerted grassroots effort – it’s designed against such efforts.
( and that’s not even considering the people who’s whole career is dedicated to working with the dnc. there’s internal dynamics which maintain a certain status quo regardless how what some elected chairperson, etc. wants. )
in a way, organizations with rules achieve a life of their own. they can only bend ( or brake ) in certain ways. if it were otherwise, they’d have no staying power as an organization. they really wouldn’t even have enough identifying features so that people could commonly talk about them.
it’s worth trying to change the democratic party. and it will change ( or die. ) but it’s not particularly reflective of grassroots interests. it’s more like a blend between monied interests and popular interests, and the money side has a pretty big thumb on the scale right now.
[ edit: after the trumpocalypse there was this statement:
We are making grassroots organizing part of the fabric of the DNC. The DNC will be restructured with a large mobilization team, full-time organizers on staff to engage directly with grassroots movements across the nation.
This will be the most aggressively unified programs that has ever been attempted. It will become the foundation upon which we will build campaigns of the future.
May 18, 2017 DNC Memo on Restructuring.
so, in theory they are trying. but the proof remains in the pudding. ]
