I did already name an edge case of popular vote that the electoral college system doesn't have (sorry, in another thread). Actually more than one. If a state has low turnout for any reason then their contribution to the election is proportionally diminished with popular voting. That DOES NOT happen with EC, because the weight of the state is decided by its population.
>You do realize that just because the popular vote is national does not mean that all the votes would be dumped at a desert in New Mexico and then tallied? Vote tally would still happen at the level of polling places and then aggregated - exactly how it's done in the electoral college system now.
I don't trust the vote counting systems we have now. We have unverified ballots by mail, voting without ID, and unaccountable voting machines. If you look into it you'll find that it is surprisingly easy to harvest votes from invalids at nursing homes, homeless people, and dead people. There is no way for me to to make sure my own vote is counted and no illegitimate ones are counted. Compare our elections that are increasingly uncertain for weeks or months to other countries like Argentina where everyone is required to vote and the result is known the next day.
