Virginia signs national popular vote bill into law, joining interstate compact with 17 other states and District of Columbia
A national majority vote for president is one step closer to reality after the 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 takes 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.



I don’t think the popular vote compact would diminish the two parties.
As far as I understand it the compact says all the states in the compact will pledge their electoral college electors to the popular vote winner.
The popular vote winner is still just the candidate with the most votes nationally so all the incentives and structures that lead to two parties are still at play.
Third parties are suppressed in a winner take all system largely due to the spoiler effect, a smaller third party pulls votes from a larger party.
Voters would still be incentivized to vote for one of the two major parties witb the same logic as today, a vote for a third party has little chance of winning and so it largely has the effect of denying a vote to the major party you would most align with.
To be clear, I think the way we’ve arranged democracy in America is quite stupid and mathematically guarantees a duopoly of parties both of which become enmeshed with and captured by the donor class. A popular vote compact is better than the goofy electoral college, I just don’t think it really does anything to break the grip of the two party system.
