Whatever you think of the electoral system, the fact that we have to wait for people to copy down those electoral votes is no longer helpful, and the fact that they can choose (or be pressured) to vote for someone else is a vulnerability in our democracy that should be patched.
You want to keep using electoral votes instead of the national popular vote? We can argue about that later. But we don’t need electors any more. Once each state certifies its election’s results, assigning its electoral votes should be automatic. It’s just math.
