This violates the important criteria of majority rule. Bearing in mind that no system is perfect and that all systems have their advantages and disadvantages, we believe that instant runoff voting is superior to approval voting for public elections for several reasons. Approval voting does not solve the spoiler problem . V oting for your second choice candidate can in some cases lead to the defeat of your favorite candidate. Campaigns would urge quietly at least their supports to bullet vote for their candidate only, and approval voting would thus tend to revert back to plurality voting.
Approval voting is unlikely to work in practice as it is supposed to work in theory.
Approval voting forces voters to cast equally weighted votes for candidates they approve of. Voters cannot indicate a strong preference for one candidate and a weak preference for another. Voters in fact almost always will have different degrees of support for different candidates. If this result were to happen the system would likely be repealed. These reasons help explain why legislation to adopt instant runoff voting is gaining such widespread support.
