Namibians are voting Wednesday in presidential elections. Among 15 candidates are 37-year-old university professor Job Amupanda of the Affirmative Repositioning (AR) party and 72-year-old Netumbo Nandi-Ndaitwah, vice president of the ruling Southwest Africa People's Organization (SWAPO). The Southern African Development Community (SADC) has called for a peaceful vote. Professor Sipho Seepe, a political analyst and former Deputy Vice Chancellor for Institutional Support at the University of Zululand, tells VOA’s James Butty, Namibia is one of the southern African countries that have been led by liberation movements following independence but are now being judged by young people on their performance.
