Old Empresario is correct.
The Electoral College was originally intended to evade the people's vote and is a direct legacy of slavery called the 3/5 compromise, during the 1787 constitutional convention in Philadelphia.
The Electoral College is an insulating mechanism between a the 1%'s super rich and the people of America. Our current political process of electing the most powerful person in the world punishes minority interests in a serious way with the All-OR-NOTHING winner take all rule that disenfranchises millions of voters.
If it's all a set-up then why are we strongly urged to vote? Because a very low voter turnout undermines the confidence of an election's legality.
Different voting systems include:
Two Round Runoff
Coombs Method (Reverse Instant Runoff)
Approval Voting (simplest cardinal rating)
Borda System (ranking)
Condorcet Voting/Pairwise Method
Bucklin Voting (first rank votes are counted first)
Preference/Hare (Choice Voting)
