Earlier quoted context omitted.
So I am not following this especially closely, but my understanding is that the vote represented a minority of the population and was done outside of legal channels. Your last question is really the most pertinent issue as far as what happens next—does the citizenry really care about this, and deeply? Or is it more of a power play drummed up by local political leaders?
It was done “outside of legal channels” in the sense that it’s not possible to do it “within legal channels”. I have no particular view on the outcome of this, but the fact that upwards of half a million protestors turned out in Barcelona suggests that it’s an important issue.
My understanding is that the polls were not universal, but only ran in the Catalonia areas with strong support for independence. And there was no vote security and verification, in fact, people were encouraged to vote multiple times in the same referendum.
So the referendum could not be construed as legal.
