Fort joins a race that's already well underway. City Councilwoman Keisha Lance Bottoms, City Councilwoman Mary Norwood, City Council President Ceasar Mitchell, former City Councilwoman Cathy Woolard, ex- city chief operating officer Peter Aman and Reed aide Michael Sterling are among the contenders in the race.
Fort said he'll bring a Sanders-style insurgency to the race.
"This is a change election," said Fort. "And the establishment of Atlanta is the status quo. It is time for a change."
