Yea, state assemblyman, state senator, and/or state representative could work. I like it as is though -- adds to the alternate reality mood.
Great mod by the way. The African ethnicities and religions are great. It would be great if the religion of mainland Afro-Anglo provinces could heresies: National Baptist Convention and the African Methodist Episcopal Church (ala Victoria 2) are two of the biggest and could work well. National Baptist Convention members were originally independent, autonomous congregations that joined to create the more unitary NBC church in the late nineteenth century -- NBC could be represented as a schism from Baptist. The African Methodist Episcopal Church is a schism of the Methodist Episcopal Church (itself a schism of Anglicanism). It was founded in the late 18th century. The majority of African American Christians are adherents of African American schisms -- only a minority are generic evangelicals. A few Caribbean provinces with these schisms would be cool too, since the African American schisms have historically proselytized there and have large presences especially in the English-speaking Caribbean.
