I belong to an org whose bylaws allow either IRV, STV, STAR Voting, bloc multi-winner STAR Voting, STAR-PR (aka Allocated Score), or RRV. (It's a lot, I know.)
A bylaws change is being proposed which would include a "None of the Below" option for any election using any of these methods. As I understand it, "None of the Below" would behave like one of the candidates. If "None of the Below" wins a seat, then the tabulation stops and no further seats are filled for that race.
For single-winner elections, I believe the effect would be identical to "None of the Above." The seat might remain empty after the election. For multi-winner elections, any number of seats might remain empty after the election.
Are there any unintended consequences that could arise from this proposal, for either single-winner or multi-winner elections? Either IRV or STAR? For example, would there be incentive to bullet vote or to min/max?
