Weighted Votes with Ranked-Choice Voting

For some online elections, it is desired to use weighted votes. In government elections, the vote of each voter counts the same so that each voter has equal influence. In this situation, you could say that each voter has a weight of one. Voters used to government elections may think that weighting some votes more than others is unfair, but there are elections where it is fair and necessary!

Probably the most common example is condominium homeowner associations or HOAs. For a building with multiple condominium units, the building will often need to make decisions, such as to charge each owner an additional fee to replace the roof. To make these decisions, the HOA will have trustees who are elected by the condo owners to make decisions. The trustees will generally be a subset of the condo owners.

Because the condos in the building have different sizes, each condo owner is assigned a weight corresponding to the size of their condo. For example, the weight of a vote may be the same as the square footage of the condo, and a person with a 2000 sq. ft. condo will have double the voting power of a person with a 1000 sq. ft. condo.
