New Mexico Gov. Michelle Lujan Grisham signed legislation Wednesday, officially joining a group of states that have agreed to elect the next president by popular vote.
The measure passed through both chambers of the New Mexico legislature with no Republican votes, according to the state’s website.
States will award their electoral votes regardless of individual state voting results.
States that have passed similar legislation to join the NPVIC now represent 189 electoral votes.
The compact could become official when that number hits 270, or enough votes to elect the president of the United States.
Under the U.S. Constitution, a state gets one Electoral College vote for each of its seats in Congress.
New Mexico is a winner-take-all state, which means it allocates all five of its Electoral College votes to the presidential candidate who wins the state’s popular vote.
If the NPVIC ever takes effect, New Mexico would instead award those votes to the candidate who wins the popular vote of the Compact.
Current Compact states include California, Colorado, Connecticut, Delaware, Hawaii, Illinois, Massachusetts, Maryland, New Jersey, New Mexico, New York, Rhode Island, Vermont and Washington.
Including the District of Columbia, there are 15 electoral jurisdictions with 189 votes.
