How would you handle Rhode Island with 4 EV? The clear victor at 55% has "about half" of the popular vote. Who gets the 4th EV?
Exactly. How do the five states that have only 4 electoral college votes split them? Not just Rhode Island, but Maine, New Hampshire, Idaho, and Hawaii. Wouldn't ME and NH always split the four EVs evenly, giving two to both candidates? At what threshold does a state that has only 4 EVs decide to split them 3-1 instead of 2-2?
The seven states that have just 3 EVs will always split them 2-1 in favor of whoever wins. No drama there. The states that have 5 EVs will very likely always split them 3-2 in favor of whoever wins.
This kind of system does not make any sense to me. The system would only be relevant in the largest states. So I prefer a NPV.
