As I recall, the electoral college was primarily for logistical reasons— a number of people come to Washington, meet together, and the outcome of that meeting determines the next President, with no appeals because the people in the room are empowered to choose.

Communication happened at the speed of a horse, so if you need a decision quickly, you can’t have electors asking for instructions from their home government. For better or worse, the founders favored a definitive result in this case over a correct one.
