Get your licks in now, I don't think it'll survive much past the November elections.
I don't know if the DUmp will go away, it might survive depending on how economical it is, but I think a lot of DemOrgs, such as MoveOn.Org, will have spent themselves out of existence.
Honestly, after ACORN and SEIU, I cannot think of any other DemOrgs and it seems the world used to be littered with them.
