Most private polls now project him winning about 30 percent of the vote, a 10-point lead over the second place candidate, but still very far from the overall majority needed to win outright and avoid a runoff scheduled for June 5.
Other candidates in the race are warning of dire consequences if Humala were to govern Peru and they all want to be the one to stop him. Mr. Toledo, 64, who only one month ago appeared on track to coast to victory and is now battling for his political life, has started running ads calling Humala a danger and saying Peru would stumble backwards at a rapid pace if he were to win.
Mr. Kuczynski is in the same boat as Toledo, but he has been trending upward and could break out if voters such as Peña make the last minute decision to vote for the 72-year-old economist and concert flautist. He has been taken to task for only renouncing his US citizenship in late March, when it looked like he had a fighting chance for an upset, but on Saturday he got a boost with an endorsement from the ruling APRA party.
Kuczynski, who was one of Toledo’s finance ministers, says a Humala victory “would be nefarious for Peru. He could waste 10 years of growth and set the country back decades.”
Toledo and Kuczynski, who are in a dead heat, may be criticizing the frontrunner, but their sights are actually set on Congresswoman Keiko Fujimori. They would need to beat her to get into a runoff with Humala. She is polling at about 22 percent, within the margin of error of most polls for either man to beat her. She has been stuck at this level most of the campaign, with Toledo dropping below and Kuczynski sneaking up on her.
