In my last game I had two odd things happen regarding my approval rating:
1) In the late game I was running at something like 80% taxes with a 57% approval. I tweaked taxes up one click to get approval closer to 51%, but approval instantly dropped to 1%! I was able to duplicate it over and over - it always plummeted to 1%.
2) I had an election shortly thereafter (with approval at 57%), which I was quite shocked to lose! How do I lose an election with 57% approval? Is there a random die roll or something?
Anyone know what was going on with either of these?
