I would like clarify the point around "basically there were a couple 'slates' of candidates for Hugo Award nomination" to point out that the two slates in question, Sad Puppies and Rabid Puppies, were allied in their perspective and thus behaved much like a single slate. If they had been opposing slates, we would have seen very different results - much like American elections where there are slates backed by the two major parties.
