We are a Federation of 50 states...not a country of 300 million people. Each state in the beginning was to make its own law and Federal power was very limited. This principal of limited Federal power is what got our great nation to form into one of the worlds grandest experiments. Unfortunately, because of the powers of the Supreme Court and abuse of Executive Power ... by many past presidents and Supreme Court cases that strayed from the views of the majority... we have deviated from the original path of our "Founders." Moving forward to this time period we have the 50 States and the District of Columbia who must come together as a nation of states and elect members to the Legislative and Executive branch every four years. Without the Electoral College...40 plus states would be beholden to the views,ideas, and social experiiments' of 10 or less states based on the population dynamics of those states.
Those 40 plus states need the Electoral College or our grand experiment fails.
