Or another likelyhood; the Federal government will no longer turn a blind eye as it has in Colorado et al under Obama, and we wind up with a full on Federal / State showdown.
Maybe, but our "states rights" republican platform now elected to run the federal government will have to perform a grand act of hypocrisy.
Not that I don't put it past them.
"States' Rights" was always a red herring, IMO. Even in the civil war, the confederate constitution explicitly banned individual states from deciding to ban slavery.
The red herring is the slavery argument your political masters have fed you to keep you happily allowing massive power consolidation to an abusive apparatus.
