It might be a mismanagement of the political factions in my empire, but I just had a Cravers game come to a crashing halt when my third election applied a blanket 30-40 happiness penalty to all of my systems, basically destroying my economy in the process. If it was mismanagement, I feel like the politics system needs a much more detailed explanation (if it was not already in planning).

I am not entirely sure where the opposition factions gained so much strength - While I had been at war with the Vodyani, my conquering strategy was raze and replace. I did assimilate a minor faction, but there's 4 non-Craver population over my empire out of 29 total population. But every one of my systems is roughly evenly split between Militarist/Scientist/Religious, which is means that there is no good election outcome for me. How could I have prevented this?
