Computer for President? This question reminds me a lot from an anime called "Psycho-Pass" where the citizens were controlled by a machine called "Dominator". It reflects your behaviour in colours pattern. If it's white you have the right to stay in the society if it is red you are "dangerous" and you do not deserve being part of it. At the end of the day this system went broken because it is impossible to determinate something as complex as human behaviour by a computer/system.
Abstract and complex theories like law, equality, legislation, governance, rights, taxes, etc... Can't be identified by a computer/robot system as a "0/1 pattern" or algorithms. It depends a lot of where are you living: Countries whose rule of law is a constitution/countries whose rule of law is God or religion (for example Morocco or Israel). So in this fact it will be impossible to determinate equality or governance since the moment where the meaning of those terms are differently interpreted by the governors.
