The National Popular Vote interstate compact (NPV) is state legislation designed to nullify the Electoral College without changing the Constitution. It has a “trigger”—NPV takes effect if passed by enough states that they control a majority of electoral votes (270 out of 538) and thus the outcome of presidential elections.

I am not sure that it will actually make any difference once things settle down.
I say this because, at the moment, many voters in states like California will not bother voting for a president if they are Republicans. They know they are wasting their time. However, if all votes counted I would expect more Republicans to vote in blue states.
