There has been a major push to eliminate the Electoral College since Donald Trump won the General Election by beating Hillary Clinton in enough States to win 270+ Electoral Votes, despite Hillary winning the General Popular Vote. This entire movement could be considered as spitting on the entire purpose of the Electoral College and the US Constitution in general. Because, this movement actually ignores the entire reason why the Constitution is laid out the way it is and why we have the Electoral College.
If you read the US Constitution, there are two themes written throughout. The first and obvious theme is Checks-and-Balances between the different sections of government. And, it actually ties in with the second theme and the entire theme of this article: Preventing the Majority from constantly getting their way. If you read the Constitution and the Amendments, in particular, the Bill of Rights Amendments; you will find the entire document rests on preventing the majority from making all the rules.
For example, the First Amendment states:
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.
This Amendment is all about protecting the rights of everyone, even if you disagree with them, and to allow people to hash out their differences with the Government as Moderator/Arbitrator. This Amendment also protects the media from being pressured into becoming a propaganda machine by any Party. It does not prevent the media from CHOOSING to become a propaganda machine.
Even the 23rd Amendment is all about preventing a majority from taking the voice away from the People:
The District constituting the seat of Government of the United States shall appoint in such manner as the Congress may direct:
A number of electors of President and Vice President equal to the whole number of Senators and Representatives in Congress to which the District would be entitled if it were a State, but in no event more than the least populous State; they shall be in addition to those appointed by the States, but they shall be considered, for the purposes of the election of President and Vice President, to be electors appointed by a State; and they shall meet in the District and perform such duties as provided by the twelfth article of amendment.
The Congress shall have power to enforce this article by appropriate legislation.
This Amendment is about granting the District of Columbia, which until the ratification of this Amendment, was without a voice in electing Presidential Electors. So, in 1961, the District of Columbia was given the ability to possibly affect the Presidential election instead of being a minority without a vote.
So, in truth, the Electoral College is about preventing a minority from having no say in the President's election as politicians running for President would just ignore the majority of the land mass of the country and because the majority should never run roughshod over the minority. That is what this country has consistently been about. Yes, even though in the beginning, the country was pro-slavery; even during the framing of the Constitution, the slave States did not fully gain what they wanted which was 1 slave equaling a person in terms of population. But, the non-slave States failed to get slavery abolished and make slaves being no part of the population to determine Representation and Electoral votes. This was why there was the 3/5ths Compromise that determined that a slave was equal to 3/5ths of a Person; because neither the majority or the minority got everything they wanted. It is this History and actual vision of the Framers that has been ignored by the "One Person, One Vote" movement. They have forgotten that majority rules ends up becoming "MOB RULE" in the end.
