According to Tennessean reporter Michael Cass, the District 19 seat (currently held by term-limited Ludye Wallace) has two more names of possible candidates to be added with Janice Davis and others that Cass leaves unnamed. Erica Gilmore, daughter of Council Member Brenda Gilmore, and Michael McDonald, who was fired from his election administrator post in 2004, both have picked up qualifying petitions for the open seat, which is to be filled in August.
UPDATE: Sean Braisted sent me a list of all of the candidates for Council who have filed so far. Janice Davis is not among the 6 who have filed. Besides Gilmore and McDonald, here are the other candidates: Cathie Dodd, Freda Player (whom Sean mentions in the comments below), James Turner II, and Maurice Walker.
