There is literally no good argument for writing a law banning this. It’s indefensible. I challenge one person to try.
I’ve been in favor of RCV for a decade+ and believe our country would change practically overnight by adopting it; however, there are legitimate reasons it hasn’t been adopted. As stated and linked in the article,
Brown and other critics of ranked choice voting contend the system is confusing, and he said there are numerous instances in which voters didn’t end up ranking their choices.
Ballot exhaustion occurs when a ballot is no longer countable in a tally as all of the candidates marked on the ballot are no longer in the contest. This can occur as part of ranked-choice voting when a voter has ranked only candidates that have been eliminated even though other candidates remain in the contest, as voters are not required to rank all candidates in an election. In cases where a voter has ranked only candidates that did not make it to the final round of counting, the voter’s ballot is said to have been exhausted. An exhausted ballot is sometimes referred to as an inactive ballot.
Whether this qualifies as “literally no good argument” I think is dependent on the number ballots where this was an issue. You could make an argument that people aren’t educated about the system or the system isn’t adaptable for all voters. Whether those are “good arguments” is perhaps subjective.
