premise: Harvard-trained Iron Lady Ellen Johnson-Sirleaf appeared to be Africa's first elected female president as results from 90.8 percent of the polling stations on Thursday gave her a commanding advantage over football great George Weah in Liberia's post-war presidential runoff.
  The 66-year-old grandmother and former finance minister had 59. 1 percent of the votes while the 39-year-old former FIFA player of the year had 40.9 percent, Frances Johnson-Morris, chairwoman of the National Elections Commission, told a news conference.
  Voter turnout was 59.8 percent from 2,719 of the 3,070 polling stations across the war-torn west African country, she said.
  "We are elated that the Liberian people have placed their trust in us, but we will not make any official statement until the final results are announced," Morris Dukuley, spokesman for the Harvard- trained economist told Xinhua.
   Why are the Liberian National Elections Commission elated?
