Although there are some scattered counties in the east that are majority Black (such as rural Noxubee), the bulk of them are White. It’s mostly those along the Mississippi that are majority Black. It’ll be interesting to see how Benton votes this year for Governor.
I go through Benton County on 72 often. I have a good number of clients from Ashland. I thought the black population of Benton was higher considering what I see on 72 from New Salem to the Marshall County line.
