What happens if both the National Popular Vote Compact and the District Method propositions are on the ballot, and both pass? Which would take precedence?
The Compact would have to take precedence...as soon as enough states pass it. You can pull out up to 6 months before the next Presidential election, so they would also have that option if both pass. But remember, a district method is no more special than the method already on the books (which the compact would clearly override). It just isn't used as much as winner take all.
