It might be shocking to some to realize that the question of whether the United States is a single country or a union of states is not decided. One would think that the question was answered at the end of the Civil War, except that the 10th amendment was not repealed. Nor was the electoral college, nor other parts of the constitution that treat states as sovereign. Consequently, we live with the reality that citizen’s votes are not equal in Presidential elections. If you live in California, your vote matters less than if you live in Ohio. It’s not right, but it’s a consequence of where one chooses to live.
Those who benefit from the status quo see the Electoral College as a feature rather than a flaw.
