In the first round of the election, held on 16 November, he took first place with 40.7% of the vote, the rest being divided between five opponents. As in 1999, Mahamadou Issoufou took second place, and he participated in a runoff with Tandja on 4 December. Tandja was re-elected in the second round with 65.53% of the vote, with Issoufou receiving the remaining 34.47%. All four of the defeated first round candidates supported Tandja in the second round. He was sworn in for his second term on 21 December at a ceremony at the Général Seyni Kountché Stadium in Niamey, which was attended by six other African presidents.
