Like assuming anywhere remotely cosmopolitan will indefinitely become more Democratic, haha.
With the exception of cosmopolitan areas that are getting large influxes of boomer retirees, I think this is a fairly reliable indicator at least in the next few cycles.
Most cosmopolitan areas are younger, more ethnically/racially/religiously diverse, often more secular, more educated, etc.
I agree in the next few cycles, but he said “permanent.” Something will shake up our coalitions in the coming decades.
Some things don't change though. Wyoming, Kansas, Utah (to some extent), Nebraska, among others, have all been Republican strongholds for their entire existence, with Kansas even resisting Democrats at the height of the Great Depression.
The educated and suburban state of kansas needs a populist like 1896 to be winnable for D's
