I always understood election as a kind of checking power over whoever is already at the power, the ultimate authority even above supreme court and president. Only problem is its not immediate but eventual. Can mass voting system replace such authority ? [ A robotic president, which will post questions for which decision needs to be taken for polling via internet, tons of people choose from the option. ]
