In Mississippi's largest city, Johnson is running for a second term. Among his Democratic opponents are two sitting councilmen — Frank Bluntson and Chokwe Lumumba. Three independents qualified for the June 4 general election.
Friday was the deadline for candidates to qualify for the 2013 municipal elections. Most cities will elect mayors and local governing boards. Some cities will elect police chiefs and city clerks.
Candidates must be registered voters living in a city. Candidates for aldermen or city council posts must live in the ward or district in which they run.
