The national popular vote interstate compact is a pipe dream.

In the extremely unlikely event it is ever enacted, it will be dissolved as soon as a supporting state realizes it is likely to affect the outcome of the upcoming election.

If it ever actually affects an election, it will likely be deemed unconstitutional at the supreme court.

Even if it is not deemed unconstitutional, states bound to vote against their own voters will withdraw from it immediately.

At most, it will directly affect no more than one election, and probably not in the direction expected.
