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.
Despite what the ballot may say, voters in the various states are voting for electors, not for president, and the votes can't be added together into a meaningful number.
You could certainly take the numbers, along with registered party affiliation and other demographic data, and historic data from more contested elections in the various precincts, and guess what the vote counts might be at various levels of turnout (including scenarios where more eligible but currently unregistered persons turn out to vote), and those guesses would likely make for a much more interesting discussion than just pointing out a number that seems like a statistical oddity.

That's not exactly true though, because of the electoral college Republicans in California don't bother to vote, since their vote doesn't count.
If you didn't have an electoral college then the popular vote count would have been different.
You can't change the rules of the game after the fact and say "look we would have won", without also considering that people would have played differently with different rules.
