One could argue that their votes would still count, as those votes would be added to the national total.
What would no longer count - electorally speaking - is Maine as a state. This ‘National Popular Vote’ idea is bad for a dozen reasons. And it’s particularly bad for smaller states. They are surrendering all their influence to the four or five largest states.
Which is exactly what the Founders were trying to prevent.
“What would no longer count - electorally speaking - is Maine as a state.”
That’s right. The founders had great respect for the roles of states as separate important entities and they went to great lengths to ensure states rights, after all it was states that originally created the federal government not the other way around.
The movement can violate the voter’s rights in the state. Assume Maine’s or Colorado, or any of the other states in this movement vote for Candidate A, but Candidate B gets the popular vote, the decision of the state’s voters is ignored.
Sounds like a lawsuit waiting to happen, and should be filed ASAP as a violation of voting rights.
