Hmm, this brings me to another idea for the game. If your approval rating drops below 100% then maybe crime rates could be increased inversely proportional. So with each point of approval rating lower than 100, your crime rates would all increase by an x amount. Perhaps each point of approval below 100 would increase crime by 0.25% or something along those lines.
I edited this because i figured i should explain why crime would go up as approval ratings go down. If the idea wasn't clear on my part, it is because in real world politics, discontent among the citizenry causes protests, riots and other anti government actions, ergo higher crimes rates. Just wanted to be clear in case anyone thinks it doesn't make sense.
