I also checked Iowa, but it turned out that Waterloo had 2 or 3. Also, Utah doesn't have a black precinct (although weirdly enough it has a 100% Asian precinct, although with 4 people). Also Rhode Island doesn't have one (41% tops). Though I also checked Colorado and Washington and they have a few.
