National Presidential Primary County and State Maps (1912-2020)

All McCain counties, except Issaquena which is very rural - the smallest population for any county in the state - but there are more blacks than whites there.

To be honest I had expected a racist like Duke to rack up good margins in places where blacks outnumber whites in any GOP primary.  I don't know how much Duke's candidacy can tell us about any of these areas though.

St. Helena Parish is 52% black, so the Republican primary electorate there conceivably would be especially extreme as a response to their perceived minority status.  Thurmond won majority black counties in areas of the Deep South which otherwise voted for Truman -- bearing in mind, of course, that blacks in these areas could not vote.
