I've got to the stage on democracy now where I can play the game and just tweak values rather than adding big new chunks of stuff. I've already changed a whole bunch of things to balance it for the btter, socialists and capitalists aren't so fickle now, and you don't automatically start off with happy socialists and angry capitalists :D
One change I made was to allow different default values for voter types. So smokers start off fairly happy, and your policies can only really upset them (but you might need them to raise revenue or to increase lifespan). whereas state employees default to unhappy and need cheering up by high government spending on schools and hospitals. I think this makes balancing the game a lot easier.
Sales of Starship Tycoon were exceptionally good today :D
