Update: Sigh. Just can't leave it at that, can I? Vestigial e-mail lists aren't always an asset, in fact, I have a hunch they're a net negative. Many of the people on the list will no longer be interested in the candidate, and many of those who might, in some world, retain some sympathy for them will have so totally conditioned themselves to junk the e-mails that they're effectively empty inboxes by the time the next campaign rolls around. Those very same people, conversely, will open e-mails from new candidates because they're not used to trashing them on sight. So it seems to me that Kerry's e-mail list is going to be less effective per person and, because so many are already on it, harder to grow. Other candidates can build their lists and enjoy much higher rates of click-through and participation from much lower numbers of people.
