That's a fair point, but three counterpoints.
1. The same people who demand that voters all be equal want to have the President elected purely by California.
2. The national vote was down 5% over year 2012; California's vote was up 10%.
3. With all its massive wealth and one-party rule, California was counting votes two weeks after every other state. We're told that extra time was required for "correcting" mail-in ballots smeared with jelly, gravy, etc.
Put those last two things together and see if the sum justifies the first, overturning the electoral college. Were we to go strictly by the popular vote, either California would select our President every election, or every state would take up finding extra votes for two weeks after the election.
