During the campaign, Patriotic Front leader Michael Sata was strongly critical of Chinese investment in the country and suggested that he would recognize the Republic of China (Taiwan). One opinion poll in September gave Sata a considerable lead over Mwanawasa, 52% to 27%, with Hakainde Hichilema in third place at 20%, but Mwanawasa questioned these results. Another poll earlier in the month gave Mwanawasa the lead with 33% to Sata's 24%, although this marked a drop from the 45% reported for Mwanawasa by a previous poll in August, and an increase for Sata, who had been at 15%.
