3 Million More Votes and you lose?

How do you receive nearly 3 million more votes than your opponent and lose the election? How is this possible and why do we accept it? Our Constitution is not by and for the Electoral College. Explain how this system is more fair? Twice we have received buffoons from this process. Twice, more people clearly voted for the other candidate, and that candidate lost. There is an easy fix for this. There is no need for a constitutional convention. If this outrage ever happens again, the electors will be charged with casting their votes for the candidate that wins the popular vote. And not all states have to instigate this. You say this isn't possible? Many states already deny the electors from changing their vote. Yes, a state can overwhelming vote for one candidate and the electors are not tied to that vote. WTF This was done to keep someone like Trump from being elected! Since it didn't work it's long past time to change the game.
