There are flaws with any system, but at least what we have now does give a wide range of views and beliefs to get involved in the selection process. If we switched to the popular vote, a few large cities would decide every election. Being as large Cities all have the exact same far left set of beliefs with no variety or nuance then that would be the bases of selecting every President.
Granted, I am sure Liberals would love this idea, but that is certainly not fair to the rest of America.
America was never meant to be a pure democracy, in fact our founding fathers specifically spoke against the idea of a pure democracy because they all fail at some point. Consider this, most Americans believe in some form of God, so a pure majority should be able to force religion down the minorities throat?
No, that is mob rule, and America was never designed for mob rule.
