Hi Sean,
I understand your point, that in most elections enabling candidates to vote in their elections woould not be a big deal.
Why that may be a problem here is that there are only 20 electors. So any individual vote can make a difference, as it has in the past in close votes.
BUT.... now that you mention it...
In this particular election, the only two candidates are BOTH eligible voters too. So, at least this time it would not at all damage the integrity of the election if both were allowed to vote; one would imagine that their votes would cancel each other out, and the remaining 18 voters would decide the result.
(should either Alan or Leon not vote for themselves I would be terribly confused.)
Similarly, if neither Leon nor Alan voted, but no replacements were chosen, a similar result would ensue.
As the NARALO-designated replacement voter for Alan, I would be happily yield back should one of these sensible approaches be adopted; that is , either both Alan and Leon are entitled to vote, or neither is replaced. Mind you, if there's something that At-Large excels at it's overly complicated processes, so I won't get my hopes up.
