In terms of having the “marrying cousins” stereotype.
Ya I would agree likely no Alabama equivalent, but I would say the closest would maybe be Saskatchewan?
Saskatchewan is the birthplace of the NDP (Canada’s social democratic party), universal public healthcare (ever heard of Tommy Douglas?), and historically one of the pillars of the labour movement. It’s now the most conservative province, but still has tons of new immigrants, racial and cultural diversity, good education, and well funded government services. The SK NDP ruled almost continuously from 1971 to 2006.
SK is much more like midwestern farm states that were formerly pro-labour pro-union hotbeds but are now more moderate or conservative, like Iowa and Wisconsin.
