You've been recently chosen to be the President of a great country. Now, you have to do things right, otherwise you'll lose your power.
Keep your Popularity, the Economy, the Religion, your Sanity, and your Political friends to continue in the presidency.
Each choice affects the city and you differently.
Any state under 25% and you'll be out. If the general state of the country goes under 50%, also means you're doing wrong.
