This one intrigues me the most. Here's a editor who's as hit and miss as it could get. Had a unstable past with quitting constantly and coming back, but that was about a few years ago. He also was involved with the Mzoli's Meats incident when Jimbo told him to leave the project because of his heavy deletionist view. He deleted Mzoli's on a rage, and came back as Secret.
He managed to rebuilt himself in the next few months before becoming the target of a massive ED harassment campaign, (I believe he was the one who either deleted the article if I'm not mistaking, correct me if I'm wrong) which let him to leave the project until recently.
If it wasn't for his prior past, he's probably one of the most qualified candidates out there. I spoke to a couple of respected administrators privately about his candidacy (and several others), and it's the one candidacy they want to see the most. I know he was involved in particular with BLP and AFD, and many people consider him to be one of the best readers of consensus, and his views are the most consistent with the direction of the project.
He won't win, but I know he is/was a favorite among many admins, but his prior past will make this candidacy the second hell hole after Jdforrester, and that's if the answers to the questions are good.
