Less than 10 days before Peru’s presidential run-off election, Keiko Fujimori of the Fuerza 2011 ticket is pulling ahead of Gana Perú candidate Ollanta Humala, according to the latest figures by polling firm Datum. Fujimori had the support of 52.9 percent of respondents, compared to 47.1 percent for Humala. This latest poll, which surveyed 1,214 people and was conducted on Sunday, indicates an increase in Fujimori’s lead of about one percentage point from the previous poll, conducted earlier this month.

Humala was scheduled to travel to Brazil today to meet with President Dilma Rousseff and her predecessor, former President Luiz Inácio Lula da Silva—after whom Humala has tried to recast his public image. However, Humala decided to cancel the trip at the last minute, according to spokesman Javier Diez Canseco, so that he could focus on consolidating popular support during the final campaign stretch. 

Humala is a former political mentee of Venezuelan President Hugo Chávez and appears to be struggling to convince voters that he has abandoned his radical-left past. Although he has vowed to govern as a moderate and has backed down on earlier proposals to increase taxes and take over private pension funds, the Datum poll showed that fully half of Peru’s voters believe Humala might govern as an authoritarian ruler. Only one-third of voters think he will honor the country’s international agreements, including free trade deals.

Fujimori, daughter of jailed former President Alberto Fujimori, enjoys strong backing by the business community, who believe she will continue the free-market economic reforms begun by her father in the 1990s. Critics feel she is too close to her father politically and over-reliant on his former aides and policy advisors.
