Basically, I have this idea for a TL where the Democratic party, in the '60s and '70s, the Democratic party pursues a 'Western Strategy' in the vein of the GOP's Southern Strategy, where they reach out to the West by emphasizing farmers issues, moderating their social stances, etc., and electing a 'prairie populist' as president. Meanwhile, I would have the GOP stick with the Rockefeller wing and become the dominant party in the Northeast while Wallace's American Independent Party fills the gap and becomes a South-centric major party. Is this feasible up to the present day? Can I have Democrats winning the Great Plains and the Rockies while the Republicans win New England and the Northeast in 2016 with this late of a POD? If so, what might a potential Electoral Map look like?
