To the best of my memory (I wish I had screenshots), the alteration has awarded d42jeep’s 7 votes to bmwrd0, contradicting my earlier assertion that they would not count and would not be transferred.
I have no opposition to bmwrd0 winning, but certainly, there is no reason to assume all (or even any) of the members who voted for d42 would have voted for bmw.
Because of the (apparently) unintended transfer, I would guess that those members cannot revote in the current configuration.
It does seem like an odd default behavior for a poll. A more logical responsive behavior to eliminating a choice would be the negation of those votes and the opportunity for those members to revote, as you suggest.
