First of all, limit the risks. Do runoff elections and split electoral votes in all states (or just don't have per-state elections it makes almost no difference). The risks now is that a 1% error can sway 100% of the votes in 5 states. It's just an unbelievably broken constitution.

If that's "too hard to fix" then there must be at least a fraction of people who don't think this is broken.

The time to fix it is right after elections.
