This election was your regular 4 year reminder that the electoral college is stupid and that the National Popular Vote Interstate Compact needs to be completed.
If I understand how the election works, the “first past the post” voting system is just as damaging. Correct me if I’m wrong, but they are not related.
I don’t disagree with your goal but I think you ought to elaborate on your arguments.
The electoral college balances geographic diversity against raw popularity. This is just one of many ways the US government gives outsized power to vocal political minorities. Perhaps explain why you don’t like things this way?
