Interesting analysis. One of many possibilities.
Eastern Washington and Oregon would prefer to be part of Red America. You've mentioned that in previous articles.
California needs to be broken up into at least three different parts. I think you've mentioned that as well. The eastern part might prefer Red America.
We have some weird boundaries in Canada as well. Provinces would be better organized as watersheds, not lines drawn by arrogant white men from the 1800s trying to increase the power base of their home province.
