Of course, the most populous states are the most in favor of NPVIC. I would expect that most of the states that are going to approve it have already done so; I expect that there will be very little further movement.

Its basically trying to game the system. The idea is that as swings occur in swing states they get locked into a popular vote if I had to guess. Probably what will happen is every time congress is controlled by republicans they will invalidate the pact which triggers a reset.

There has been a lot of talk about working from home becoming the new norm and living within 1-2 time zones of your work. It's possible in that scenario for a lot of heavily-populated blue cities to disperse, even if it's only 10%-15% of their population, into what are now known as the 'Red States' and make them 'Blue.' I know I'm interested in doing that. I can move someplace where my quality of life is better and I can afford a better home. It's going to be interesting to see how the demographics change at the end of this pandemic.

From my link:

Some supporters and opponents of the NPVIC believe it gives one party an advantage relative to the current Electoral College system. Former Delaware Governor Pete du Pont, a Republican, has argued that the compact would be an "urban power grab" and benefit Democrats.[19] However, Saul Anuzis, former chairman of the Michigan Republican Party, wrote that Republicans "need" the compact, citing what he believes to be the center-right nature of the American electorate.[33]

A statistical analysis by FiveThirtyEight's Nate Silver of all presidential elections from 1864 to 2016 (see adjacent chart) found that the Electoral College has not consistently favored one major party or the other, and that any advantage in the Electoral College does not tend to last long, noting that "there's almost no correlation between which party has the Electoral College advantage in one election and which has it four years later."[32]

Will be interesting to see how that trajectory changes post-COVID with so many companies forced into remote. For me, my company moved full-time remote and because of that my home search has expanded outward
