If voters have single-peaked preferences, the majority rule always leads to the selection of the median ideal policy. This is because the median policy is the one that maximizes the sum of voter utilities, as it is preferred by more voters than any other policy and any policy to its left or right would have fewer total supporters. Therefore, the majority will ultimately converge on the median policy as the most preferred option.
