So I take it the critics of ACORN would like it to have more money so that it could pay higher wages to its workers, and could afford to keep open offices which weren't registering that many people? That sounds fine to me.

The bottom line should be that, one way or another, everyone who is entitled to vote needs to be registered, and that registering voters should not be seen as a partisan exercise, but as something that a democratic society has a absolute duty to ensure is carried out effectively.
