Dems become more religious and further left on economics and social issues, republicans become irreligous and focus on an "anti-bureaucracy" platform, libertarians want less government regulation on businesses, laxer gun laws, while the trumpists want less rules and regulations for police officers, less regulations on racial profiling etc.
While the first is kind of dubious, the second is very likely to happen. Or were you referring to "becoming more religious" and moving "further left on social issues" at the same time?
GOP attracting irreligious voters and Dems attracting Mormons is plausible at the very least. The only issue I have with this map is LA and MS being Solid Dem, but I'll give BernieBro the benefit of the doubt. I don't see the contradiction between "religious" and "socially liberal" because I think the wedge social issues among my generation will be different from those of the recent past.
