Some things I have not heard in the media, but are worth noting:
1. To say that Hillary “won the popular vote” is not exactly true. As of today, Hillary has about 47.7% of the votes counted so far. She has a plurality but not a majority of the votes cast.
2. Al Gore also got less than 50% of the popular vote, when he “won the popular vote”.
3. Campaigns would be run differently, if the popular vote was the deciding factor. California, for example, was completely ignored in the general election, because both candidates knew the state would go Democrat. Trump might have spent some time in California to chip away at the popular vote margin in California, if it would have made a difference; if the popular vote total meant anything, legally speaking, in deciding the election.
