I've voted Dem all my life (since 1988), and while my preferred candidate has won several of those races, my actual VOTE never helped them because I voted in Mississippi (88), Alabama (92), and Texas (96 & thereafter) -- all of which have been GOP strongholds for a long, long time. (Texas, for example, hasn't gone for the Democrats since Carter v. Ford in 1976.)
It's easy to imagine that a feeling of despair about the efficacy of one's vote would drive someone to stay home.
Not saying it's great, but maybe it's not too dissimilar from some other systems?
The electoral college - and the Senate - were intended to explicitly put power in the hands of the states, as equals, without regard for population. The House of Representatives was intended to be the counterbalancing voice of the People.
I can totally understand disagreeing with the concept, but to say it's stupid tells me you likely don't understand its purpose and how it fits into the overall system.
The U.N. doesn't directly elect the general secretary.
If DJT ends up with a final popular vote advantage, though, it'll be the first time that a Republican has taken the Oval Office AND the popular vote since 1988.
Blue voters in states that are absolutely going Blue may also stay home.
That's true, but I don't think Democrats had a feeling of despair before the results came in. It seems like most Democrats are shocked that the election turned out this way.
