The Sad Puppies won. Yes, they didn't win a single award -- in fact, some really good works lost to No Award, seemingly just to spite them.
But that was the point.
Their stated goal was to prove that there was a group of people out there voting for political reasons and fixing the Hugos... They proved the Sad Puppies point -- that the Hugos are fixed by a group of gatekeepers.
Did they? Or did they prove that the Hugos could be fixed by a group of gatekeepers?
Specifically, we can certainly both agree with the latter - the SPs acted as a group of gatekeepers to fix the nomination slate, proving it was possible. But the fact that they did so easily and completely implies that there was no opposing force. If there already was a group of SJW gatekeepers blocking unapproved nominations, then we would have heard about a nomination battle, no? Each side of gatekeepers would rally supporters trying to control the slate, and this would become more and more public as their forces grow. Most likely, the resulting slate would have some extremist SP nominations and some extremist SJW nominations, no?
Instead, without even a breath of resistance, the SPs controlled the slate. That shows it was possible, but also shows no one was trying to do it before them. The SPs actually proved that there wasn't a group of people fixing the Hugos until they came along.
