Here's some food for thought. Assuming political realignment happens in the near future, what would the electoral map look like (15-25 years from now)? I imagine partisan loyalties would lie more with income than race and religion. I suspect demographic groups would vote like this:
Solid Democratic (Lower Income) Poorer Whites, African Americans, (Hispanics?) & Millennials
Solid GOP (Upper Income) Wealthier Whites, Asians, Boomers & Gen X
I assume there would be a lot of swings states. Thus, the electoral map would be prone to more wild swings (Eisenhower/Johnson/Nixon style).
Discuss with maps.
