The National Popular Vote Interstate Compact (NPVIC) is a proposed workaround to the U.S. Electoral College that operates entirely within existing constitutional rules. Rather than abolishing the Electoral College — which would require a constitutional amendment under Article V — the compact uses each state's plenary authority under Article II, Section 1 to direct how its presidential electors are chosen. Member states agree, by statute, to award all of their electoral votes to whichever presidential candidate wins the most popular votes across all 50 states and the District of Columbia.
Crucially, the compact only takes legal effect once the cumulative electoral votes of member states reach 270, the threshold needed to win the presidency. Until then, member states continue to allocate electors under their pre-existing winner-take-all rules.
The compact was first proposed in a 2006 book by John Koza and others, and Maryland became the first state to enact it in 2007. As of the mid-2020s it has been adopted by a number of states and the District of Columbia, though the total has remained below the 270-vote threshold and the membership has skewed heavily Democratic-leaning. Notable later additions include Colorado, whose membership was upheld by voters in a 2020 referendum (Proposition 113).
Legal scholars debate two main questions:
- Compact Clause: Article I, Section 10 requires congressional consent for interstate compacts that affect federal supremacy. Supporters argue NPVIC does not require consent because each state is exercising its own electoral authority; critics disagree.
- Enforceability: Whether a member state could withdraw close to an election, and how Chiafalo v. Washington (2020) — which upheld state power to bind electors — interacts with the compact.
For MUN and IR researchers, the compact is a useful case study in subnational coordination to alter national outcomes without amending a constitution, comparable in logic (though not in substance) to EU member-state coordination mechanisms.
Example
In 2020, Colorado voters approved Proposition 113, making Colorado the first state to ratify its NPVIC membership through a statewide ballot referendum.
Frequently asked questions
No. It only activates once member states collectively control at least 270 electoral votes. Until that threshold is met, members continue using their existing winner-take-all allocation.
