Electoral College - In an ideal representative democracy, leaders are elected on a one-person, one-vote basis. However, the framers created the Electoral College for selecting the president. This emanated from the framers' mistrust for majoritarian democracies. This was also aimed at curbing the domination of folk from huge states.
Checks and Balances - The majority are supposed to determine the course of action in any democratic government. However, the framers established a meticulous system of checks and balances to prevent either of the three branches of government: executive, judiciary and Legislature from dominating the other two.
