The problem here is that misery (certainly lefty misery) craves company.
California being lefty all by its solo self? There’s no fun in that. None at all! Gotta drag the whole rest of the country into it, kicking and screaming! (Which won’t happen now that Trump roolz.)
California lefties, denied all their former Federal tentacles by a yuge Trumpian swamp-draining that will depend on California about as much as his own election did, will mope... but they will be powerless.
For the good of everyone, CA needs to leave.
They are always talking about the greatest good for the greatest number, right?
