Yes, the majority of the population in the US is in the northeast, that’s why people hate the electoral college system. It gives a significant amount of power to a majority voting minority. A better way to represent a minority would be a ranked choice system.
Electoral college vs ranked choice voting is a false dichotomy. You can do one, the other, both, or neither.
The way to eliminating the electoral college, since it is enshrined in the constitution, is either a constitutional amendment changing to a popular vote method (highly unlikely), or the National Popular Vote Interstate Compact.
And both ways involve the states that benefit from the disproportionate power choosing to give it up.
