The measure … generalizes standard pivotality-based voting power measures for binary elections, such as Banzhaf power. At the same time, the … symmetric power order to show that pivotality only measures voting power in monotonic elections, and is not a good measure in …

In his seminal Social Choice and Individual Values, Kenneth Arrow stated that his theory applies to voting.
