The "popular vote" is not the will of the people:

a) the rules of voting are clear, this is both the will of the people, and is also what the people are expected to accept as citizens. The time to denounce or change those rules is before your guy loses.

b) the popular vote is not the entire country, because not everyone voted. Not only do campaign strategies and other factors affect those numbers (to a degree that might make up the difference), but if you argue that people who didn't vote simply lost out, or don't count in deriving "the will of the people", then you could just as well argue that so did those who lost to the electoral college system.
