All three of the candidates would do a great job. Given that, and basically for the same reasons that this election was bumped up to run earlier, can we have multiple winners?
You could... Although, given there are only three people running I'm not sure you could call them "winners" at that point; maybe "fine, community-minded people who volunteered to moderate".
You don't really need three more moderators though. You definitely need one; you might need two, and we can always ask the runner-up here if he wants to help if that turns out to be the case. But three new mods - 7 total - seems excessive.
That's not to knock the qualifications of anyone running in this election, btw - but it does mean you'll have to make a choice: who do you think is the best of the best?
