I think CO is the one Bush/Bush state that's completely gone for Republicans at the presidential level. Not saying that Democrats should take it for granted, but if I had to guess I would say it votes Democratic for the next 5 elections at least. It will probably start voting to the left of NM soon.
I could see this as a Republican landslide map in 2028:
You say that, but VA (a Bush/Bush state) is Democratic in your GOP landslide map.
Anyway, I like the fact that most regions of the country have red, blue, and swing states. There are exceptions (the Northeast has a handful of swing states, depending on if you count PA, but no solidly GOP state) but it's still cool that regions like the South, Midwest, and Mountain west are all to some degree politically heterogenous.
