Madison and Hamilton created the Electoral College for specific reasons… and suppressing minority voters was not one of them. Plurality is part of the Federal electoral process, but integrated to meet the needs of federalism. States matter in our compound republic. Madison wanted them involved in the process of choosing the executive.
Madison said, “The executive power will be derived from a very compound source. The immediate election of the President is to be made by the States in their political characters. The votes allotted to them are in a compound ratio, which considers them partly as distinct and coequal societies, partly as unequal members of the same society.” – Federalist #39
Hamilton saw the dangers in misguided passions leading the electorate astray, “The choice of several, to form an intermediate body of electors, will be much less apt to convulse the community with any extraordinary or violent movements, than the choice of one who was himself to be the final object of the public wishes. And as the electors, chosen in each State, are to assemble and vote in the State in which they are chosen, this detached and divided situation will expose them much less to heats and ferments, which might be communicated from them to the people, than if they were all to be convened at one time, in one place” – Federalist #68
Think of the electoral vote this way… In the 1960 World Series, the New York Yankees outscored the Pittsburgh Pirates 55-27 and out-hit the hapless Pirates 91-60. Using the rationale of plurality as demanded by the national popular vote crowd, the Yankees were clearly world champs that year. But runs are integrated into games, and in 1960, the Pirates won 4 games, the Yankees 3. Runs and hits are part of a process, but the process integrates all parts of the sport into choosing a winner.
