The chief election official of each member state shall designate the presidential slate with the largest national popular vote total as the "national popular vote winner."
The presidential elector certifying official of each member state shall certify the appointment in that official's own state of the elector slate nominated in that state in association with the national popular vote winner.
At least 6 days before the day fixed by law for the meeting and voting by the presidential electors, each member state shall make a final determination of the number of popular votes cast in the state for each presidential slate and shall communicate an official statement of such determination within 24 hours to the chief election official of each other member state.
The chief election official of each member state shall treat as conclusive an official statement containing the number of popular votes in a state for each presidential slate made by the day established by federal law for making a state's final determination conclusive as to the counting of electoral votes by Congress.
In event of a tie for the national popular vote winner, the presidential elector certifying official of each member state shall certify the appointment of the elector slate nominated in association with the presidential slate receiving the largest number of popular votes within that official's own state.
If, for any reason, the number of presidential electors nominated in a member state in association with the national popular vote winner is less than or greater than that state's number of electoral votes, the presidential candidate on the presidential slate that has been designated as the national popular vote winner shall have the power to nominate the presidential electors for that state and that state's presidential elector certifying official shall certify the appointment of such nominees.
The chief election official of each member state shall immediately release to the public all vote counts or statements of votes as they are determined or obtained.

Any member state may withdraw from this agreement, except that a withdrawal occurring 6 months or less before the end of a President's term shall not become effective until a President or Vice President shall have been qualified to serve the next term.
The chief executive of each member state shall promptly notify the chief executive of all other states of when this agreement has been enacted and has taken effect in that official's state, when the state has withdrawn from this agreement, and when this agreement takes effect generally.
