Being a bit bullish on the geographic shifts of population & banking on the GOP ultimately getting its social act together:
Pro-government and anti-government philosophies remain virtually the same as they are today and are the primary driving forces for underlying social themes within each party's economic policies. As such, the urban/rural divide only grows.
Areas that have lost out on the past decades of growth and prosperity due to shrinking populations have in traditional fashion turned toward the Republican Party, which has solidifed areas such as Ohio, Michigan and & Pennsylvania into reliable Republican states.
Likewise, stable rural states where many residents can sympathize with the concepts of small government decoupled from a regressive social message have swung hard to the Republicans, including states like Montana, the Dakotas and even Hawaii. Most of the Northeast is lost for this reason in combination with the aforementioned issue of general decline.
Areas that have enjoyed booming growth and in many cases, a diversification of their electorates, have generally found their way into the Democratic fold. New Mexico and Nevada are two of the strongest Democratic states at this point, as well as Virginia, Maryland, Delaware and New York. States such as Florida and Georgia have enjoyed majority-minority electorates for 15-20 years by this point. West Virginia has enjoyed a boom of prosperity thanks to the ever-expanding megalopolis. Illinois and New York remain Democratic strongholds due to their heavily urbanized clusters.
