Exhausted ballot: Difference between revisions

If at any point the voter did not rank a next choice (assuming her most favored choice or choices are eliminated), or all of the choices on the voter's ballot have been eliminated, the ballot is “exhausted” d meaning that it is excluded from future vote redistributions, and it does not affect the final outcome of the election. The ballot, in essence, is discarded. The process ends once a candidate receives a majority of the remaining valid votes.

 

These occur when all the choices a voter has marked are eventually eliminated and their ballot has no active choices remaining. We should note that because of inactive ballots, the "majority" 50% in RCV can refer to a majority of active ballots, and not necessarily to 50% of the original number of ballots cast.

We believe RCV works best when voters complete all of the available ranks and communicate their complete priorities. But voting is voluntary in the United States, and if a voter does not wish to make a rank, they are free not to - even if that means denying themselves a chance to make their 2nd, 3rd, 4th, etc. choice known and possibly decisive in an election.

A voter may not wish to provide any support to candidates whose policies they strongly object to - even when that support is only relevant once all of the candidates that voter prefers have been eliminated from the race. We disagree that an inactive ballot is necessarily a sign of a voter not understanding how to take advantage of all that RCV has to offer. If a local election is about an incumbent doing a good job or not, some voters might be highly invested in the incumbent, and may not have strong feelings about any of the challengers.

Imagine three candidates in a conventional election. The polls closed at 7 pm and the first precincts reporting show the race with two candidates at 40% each, and one candidate is way behind with just 20%. The counting for the 40%/40% race will probably go long into the night, and the voters who supported the 20% candidate realize their candidate can't win, and their vote is not relevant to the ongoing count. Whatever criticisms there are for exhausted or inactive RCV ballots, they should also be applied to the situation for conventional plurality elections we just described. In any race with more than two candidates, not every vote can matter right up until the finish line.

The percentage of inactive/exhausted ballots can depend on how close an election is, how many candidates compete, and how many rounds of counting are necessary for a winner to be declared. An example of a high number of inactive ballots is the very large and competitive 2014 race for Oakland, CA Mayor. Sixteen candidates competed, and it took all 16 possible rounds of counting for a winner to be declared. After three rounds of counting, the number of inactive ballots was 0.01%. By round 10, they reached about 1%, 7% in round 14, 14% in round 15, and then jumped to 24% in the final and 16th round of counting. It was in that final round the incumbent mayor was eliminated, and it seems only half of her large number of (possibly overconfident) supporters filled in a 2nd rank.

A more typical situation is the 2018 election for Mayor of San Francisco. Nine candidates competed, and the election required nine rounds of counting. After five rounds of counting, just 0.01% of ballots had become inactive/exhausted. After the final and 9th round, 8.4 % of the original set of ballots had run out of ranks.

* The voter doesn’t rank all candidates, and all of their ranked candidates are eliminated during the round-by-round count. Also known as '''voluntary abstention''', this is the most common source of inactive votes.

* Election administrators limit voters to a certain number of rankings, such as three, and all of their ranked candidates are eliminated during the round-by-round count. This is known as '''involuntary exhaustion'''.
