>>Is there any value at which you would say that, whether it's our historical system or not, the difference between the popular vote and the electoral vote is so large that it casts doubt on the legitimacy of the outcome?

This focus on "popular vote" doesn't make sense- because there's no precedent for the latest definition of "popular vote" actually meaning "national tally." People should say what they mean: if people want president to be selected by national tally, they should say so and it should be about next time, not a device to legitimize undermining a result you don't like.

As a reminder, here's what Hillary had to say about not accepting the result:

"That’s horrifying. Let’s be clear about what [s]he is saying and what that means. [S]he is denigrating — [s]he is talking down our democracy. And I am appalled that someone who is the nominee of one of our two major parties would take that position... It’s funny, but it’s also really troubling. That is not the way our democracy works."

Focusing on the newfound fascination with national tally instead of popular vote: that is not the way [y]our democracy works. There's no national tally for Republican vs Democrat in House or Senate. It's all at state level: you get to vote for your state's representatives/senators. Popular vote prevails in your state or county: the candidate/s with most votes, wins. The same equation operates in House and Senate: popular vote (meaning the majority of elected candidates) prevails, controlling House or Senate. Popular vote wins from start to finish but national tally is irrelevant.

This is a direct parallel to voting for president. There's no national tally and you're not even voting for president. You're voting for your state's electoral college members. Popular vote prevails in your state: the majority selects the electoral college members. The college then votes for president with their popular vote prevailing.

So, why are people denigrating and talking down the democracy by focusing on national tally as a device to cast doubt on the legitimacy of the result?
