You still haven't touched on what the post you're replying to is pointing out, which is that people behave differently when the rules change. A Californian Republican may as well not vote at all. If it went off national popular vote, then those Californian minority voters would still have a reason to make sure their vote was counted.

Regardless, it's a moot point, because according to the Constitution as written, those electors are supposed to only be accountable to themselves. The idea being the community electing the most level-headed and educated amongst them to make the decision everyone else would be okay with.

Most states don't respect that intent since the formation of the Party system, so really what we have now is little more than an abomination completely unintended by the Founders.
