...is that even if we get a victory, we're not done.
You don't get to just blow up the Death Star and go home. That's the kind of thinking that gets you frozen in carbonite. I mean, sure - stop and celebrate. If we pull it off, we'll have put a big damper on the Empire's ability to just go around blowing up planets. But they'll still fall back on fleets and stormtroopers and Imperial bureaucracy. We'll still need to keep working to minimize the damage that they're trying to do.
They're not going to stop. Even if we do blow up the Death Star -- and that's not even remotely guaranteed -- they're just going to try to build another one. So we have to stick with it. We have stay organized and keep up the opposition. (And we can't keep expecting the murder-bears of Endor to save us, either.)
So get out there and vote today, but be ready to keep at it tomorrow (or day after, or the day after that -- it's okay if you need a bit of a rest after all this).
(I mean, we all know perfectly well that Luke and Han and Chewbacca all went down to the cantina and got thoroughly drunk and then slept for like fourteen hours after they got back to the Rebel base, right? There was some serious recuperation time between Blowing Up The Death Star and the Victory Awards Celebration.)
