https://en.wikipedia.org/wiki/National_Popular_Vote_Interstate_CompactThis is a compact among states that says, once their number reaches 270 EV, their Electoral College representatives would be bound to select the winner of the national popular vote for President of the United States.
Basically, it's a way to effectively abolish the Electoral College for a Popular Vote, but without a constitutional amendment.
The states who have passed it so far are:New York
California
Illinois
Washington
Massachusetts
Vermont
Maryland
New Jersey
Rhode Island
Hawaii
(plus DC)
That's 165 EV. They need 105 more EV.
What are the chances of more states joining soon?
What's the path to 270?
