Senator Jim Nwobodo of Enugu East Senatorial Zone, Enugu State was not elected under AD. He was elected unopposed on the platform of the PDP when the previous winner, Uche Nnaji of AD stepped down before the inauguration of the 4th Senate in 1999. The bye election that followed Uche Nnaji's withdrawal paved the way for Jim Nwobodo to be elected unopposed on the platform of The Peoples Democratic Party (PDP). Please correct this for the records.
