On November 13, the Prohibition Party nominated its national ticket for 2020, via a telephone conference call. Bill Bayes of Mississippi is the presidential nominee. Connie Gammon of Tennessee is the vice-presidential nominee.
An earlier version of this post said Bayes is the first presidential nominee from Mississippi, but the Constitution Party of Texas in 1960, and the Reform Party in 2008, also had presidential nominees who lived in Mississippi. Thanks to the commenters for pointing this out, especial Rick Knox.
