Mill and other rule utilitarians would judge your vote based on the precedents you based your vote on. The process of determining social rules begins with accurately describing the rule. We must then imagine what a community would be like if this rule were accepted and followed by all the citizens of said community. Finally, the question must be asked: Would this society be happier if this rule were passed than any other law (Johnson, “Consequentialism” 18). In this situation, you followed the rule of voting for the bill that would most increase the utility of the citizens of your community. Seeing how this rule is essentially the basis of utilitarianism, Mill would consider it morally correct to follow it: therefore, your action was absolutely moral even if the outcome was not what you had desired.
