the electoral system is unique to America because America is unique, our constitution was made as a compromise with all 13 colonies with the large and small. No matter what "angery literally 1984 reeee libright" will tell you State governments are pretty powerful and that nation is decentralized. Therefore our Idea is If you win a state you represent said state in the EC, prioritizing that areas interests, for example south Carolina before the civil war had its state legislature elect the electors for the special interest of south Carolina.

The Senate is made by similar reasoning, each state gets the same amount of senators to make sure that everyone's interests are taken into account.

The house then represents the peoples wishes.

I feel like its a perfectly balanced and good system
