This is interesting - the Issue is not about repealing the electoral college, but by-passing it by assigning a State's electoral college votes to whichever candidate wins the Popular vote, regardless of how the State's population votes:
Colorado has become the latest state — and the first swing state — to join a group pledging to elect presidents based on who wins the national popular vote.
Eleven other states and the District of Columbia have signed onto the National Popular Vote Interstate Compact, an agreement that requires those states to select their presidential electors based on who wins the most individual votes nationwide, regardless of which candidate wins in the state.
12th Amendment governs the Electoral College - but no mention of how States assign their EC voters; Text follows
The Electors shall meet in their respective states, and vote by ballot for President and Vice-President, one of whom, at least, shall not be an inhabitant of the same state with themselves; they shall name in their ballots the person voted for as President, and in distinct ballots the person voted for as Vice-President, and they shall make distinct lists of all persons voted for as President, and all persons voted for as Vice-President and of the number of votes for each, which lists they shall sign and certify, and transmit sealed to the seat of the government of the United States, directed to the President of the Senate;
The President of the Senate shall, in the presence of the Senate and House of Representatives, open all the certificates and the votes shall then be counted;
The person having the greatest number of votes for President, shall be the President, if such number be a majority of the whole number of Electors appointed; and if no person have such majority, then from the persons having the highest numbers not exceeding three on the list of those voted for as President, the House of Representatives shall choose immediately, by ballot, the President. But in choosing the President, the votes shall be taken by states, the representation from each state having one vote; a quorum for this purpose shall consist of a member or members from two-thirds of the states, and a majority of all the states shall be necessary to a choice.
And if the House of Representatives shall not choose a President whenever the right of choice shall devolve upon them, before the fourth day of March next following, then the Vice-President shall act as President, as in the case of the death or other constitutional disability of the President.

The person having the greatest number of votes as Vice-President, shall be the Vice-President, if such number be a majority of the whole number of Electors appointed, and if no person have a majority, then from the two highest numbers on the list, the Senate shall choose the Vice-President; a quorum for the purpose shall consist of two-thirds of the whole number of Senators, and a majority of the whole number shall be necessary to a choice. But no person constitutionally ineligible to the office of President shall be eligible to that of Vice-President of the United States.

(Note: This provision was superseded by Sections 1 and 3 of the Twentieth Amendment in 1933.)
This NPV compact is a round-about way to subvert the Constitution and EC without a Constitutional Amendment, and subvert to popular vote in a State which goes against the majority Vote.
Sounds like a Constitutional Supreme Court Case to me.
I wonder where the Conservative court challenge stands to this, if there is one, a court challenge is deserved.
And More DPST dirty tricks to subvert our Constitution as written.
