In an election, the utilitarian winner (UW) is the candidate who would maximize the utility of the voters (the utilitarian welfare function) if they won.[1]

Cardinal voting systems are based on the concept of maximizing cardinal utility, having voters express their estimated utility by scoring the candidates.

In most cases, the utilitarian winner and the Condorcet winner (CW) are the same, though it's possible for them to be different.[2]

Advocates of cardinal systems consider the UW to be a better outcome than the Condorcet or a majoritarian winner.[3]

The theory of this paper suggests that the best outcome is the candidate who would win a utilitarian vote (utilitarian winner), the worst is the candidate getting the worst score in a utilitarian vote (utilitarian loser).

We show that if the statistical distribution of utility functions in a population satisfies a certain condition, then a Condorcet winner will not only exist, but will also maximize the utilitarian social welfare function.
