I don't think you really understand what the electoral college is, and the fact that without it, many states would have seceded from the US by now. At the very least, they would have attempted to, likely triggering another civil war or two in the nation's history.
Despite what some would have you believe, the American civil war was not actually about ending slavery - although slavery was a relevant factor, ending it was merely a tactic to weaken the South. When the North started trying to dictate laws to the South (including trying to make slavery illegal), the southern states attempted to secede from the union. The civil war was actually started to force those states to remain, while those states were attempting to secede in order to maintain their own freedom. (Quite hypocritical of them, of course).
If there were no electoral college, then the two states with the largest populations, California and New York, both heavily liberal, would have the power to start dictating the rules to every other state, who would have absolutely no say in governing the country. California alone has a higher population than the 25 lowest populated states, most of which provide the majority of food to the US.
If you've seen the 'Hunger Games' movies, think about how the country/continent of Panem is set up. One big rich city, filled with the liberal elites, that dictates over the rest of the country, which is separated into zones (states), in a very fascist manner. Those other zones are treated like slave plantations for different resources, with no say in how the people live their own lives, let alone how the country is run.
