OPA intern (used by various interns)
I'll come back to the actual contents of the list later. But for now I'd like to speculate wildly about the remaining 13 people--the people who'd bring us up to 50 the RNC has assured us have off-the-books accounts..
I've helpfully bolded the names of the people who aren't explicitly related to Rove (the Office of Strategic Initiatives reports to Rove, so I've left them off).
Two things stick out. First, Laura's minder (and the scheduler) has an RNC email account. Given the amount of barnstorming she does, that may be easily explained. But it is notable that Laura's got her own off-site email access.
Then there's the other interesting category. We've got Mel Raines, who used to work for Cheney but is gone. Lauren McBrien, who also used to work for Cheney. And finally, Cathie Martin, who is listed under her current curious title (given her appearance in the USA purge emails, she's definitely com. But we also know she was using her WH email to talk about firing USAs), but who also, surprise, used to work for Cheney. How remarkable, that such a significant chunk of the non-Rove RNC emailers used to work for Cheney--but no one who currently works for Cheney appears on the list.
I'm going to make one of my patented outtamyarse guesses and say most of the remaining lucky 13 still work for Cheney.
It would make sense. It would be just like Mr. Fourth Co-Equal branch to refuse to turn over the names of his associates with the off-site accounts--after all, he won't even let his staffers' names be published, and to list them here would require actually ... naming them. Then there's the matter of the 250 pages of emails "not archived in the normal fashion." And there's Jenny Mayfield's remarkable prescience in leaving any email searches to David Addington, rather than searching herself. Besides, I just think if one of Bush's puppet-masters had off-site email, the second would insist on the same privilege.
