I get what you are saying, but let's be realistic here: even with an unfair vote you could still get people out to vote and get the majority. If we could have done that then MAYBE we'd have a point here.

But reality: Bernie was really popular with the 18-36 demographic. But they don't turnout to vote in the general election, let alone a primary. So here we are. Old people get their way because they show up.

And I'm not saying Bernie didn't energize voters: just that it's a really high bar to energize that to a point of participation.
