Maine’s Senate has voted 19-16 to join the National Popular Vote Interstate Compact. If the Maine House of Representatives also approves the bill, Maine will join the fourteen states plus the District of Columbia that have pledged to award their electoral votes to the winner of the national popular vote once states with 270 total electoral votes join the Compact, thus guaranteeing that the winner of the national popular vote will become the president.

Currently, the Compact has 189 electors pledged. With the addition of Maine’s four electoral votes, the Compact will have 193 votes.
