Virginia governor Abigail Spanberger signed the national popular vote bill into law, joining an interstate compact with 17 other states and the District of Columbia. Under the National Popular Vote Interstate Compact, states would assign their presidential electors to the winner of the popular vote, regardless of the results within the state.
The compact goes into effect when states representing a majority of electoral votes – 270 of 538 – pass the legislation and thus would determine the winner of the presidential contest. With Virginia, the compact now has 222 electors. Every state that has so far enacted the compact has Democratic electoral majorities, including California, New York and Illinois. But legislation has been introduced in enough states to reach the 270-elector threshold, including swing states like Arizona, Michigan, Nevada, New Hampshire, Pennsylvania and Wisconsin.
There are legal arguments both in favor of and opposed to potential pacts.
The text requires states to gain the assent of Congress to enact a compact. But longstanding SCOTUS precedent holds that states only require congressional approval for a compact if the agreement infringes on federal power. Supporters of the National Popular Vote Interstate Compact argue that the delegation of electors is a state power, not a federal power.
