Nesmith-Joyner noted that the city has incurred more than $20 million in direct and indirect costs, received more than 3,200 machines, signed a lease on a warehouse for the machines, and held more than 150 public demonstrations of the new systems. Given how deep into the rollout the city is, she wrote, restarting the process would mean the city could not have new systems in place for November’s municipal election. (The city’s final shipment of voting machines is scheduled for Friday.)
