>>OTOH, Dems won the Senate vote significantly. However, that's somewhat misleading, because the primary system they use in California means that two Democrats were contending for the seat there. (And, of course, only a third of the Senate is up in any year.)
So can you show me the burning of flags and angry "not my Senate" protests?
As I said, these calculations are merely sidenotes of no relevance to what it says on the scoreboard according to the rules. Except when it comes to Trump.
Don't like the rules? Protesting the result is antisocial. Organizing for electoral change is the answer, preferably via representatives who can do something about it if that's what their voters say.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
