Line 184:
=== Ways of dealing with equal rankings ===
* Disallowing them, requiring full rankings
*Giving one vote to one of the top-ranked candidates, and giving no vote to the other top-ranked candidates (likely best done by choosing randomly which top-ranked candidate gets the vote)
* ER-IRV (fractional): Counting a ballot with N top-ranked candidates as 1/N of a vote for each candidate.
* ER-IRV (whole votes) or Approval-IRV: Giving one vote to each equally-top-ranked candidate. Can optionally be combined with a suggestion that ballots that equally rank candidates shouldn't be able to prevent the elimination of those candidates.<ref name="reddit 2011">{{cite web | title=Proportionality failure in STV with equal-ranks with whole votes : EndFPTP | website=reddit | date=2019-12-05 | url=https://www.reddit.com/r/EndFPTP/comments/e6bt6s/proportionality_failure_in_stv_with_equalranks/f9thuy4/?context=8&depth=9 | access-date=2020-02-10}}</ref>
