Awwa 25, 1432 /April 29, 2011, SPA -- one of the world's fastest-growing economies, holds a run-off presidential election on June 5, Reuters reported. The latest poll shows left-wing nationalist Ollanta Humala and right-wing lawmaker Keiko Fujimori are virtually tied, with around 20 percent of voters undecided or planning to abstain. Humala, 48, a former army officer, has moderated his campaign message since narrowly losing the presidency in 2006 but polls show many voters continue to believe he would pursue a nationalist agenda if elected. Fujimori, 35, is the daughter of jailed former President Alberto Fujimori. She pledged to respect human rights if elected. Both candidates want to tax windfall profits of mining firms and appeal to poor voters, around 35 percent of Peruvians.
