In Peru, a populist former army officer has seen his lead increase in the country’s presidential race. Ollanta Humala now leads all candidates with just over 30 percent of the vote. Lourdes Flores, a former congresswoman heavily backed by Peru’s business community, is in a tight race with ex-president Alan Garcia for second-place. One of them will likely go up against Humala in a runoff vote next month. Humala has been bitterly opposed by Peru’s business community. On Sunday, he and his wife were trapped for more than an hour by rock-throwing protesters when they tried to vote in a wealthy neighborhood of Lima.
