LIMA (Reuters) - Peru's presidential election race is tightening a month ahead of a run-off vote in June, with socialist Pedro Castillo still ahead, while pollsters say the key battles are in poor, rural regions and in convincing a large group of undecided voters.
Frontrunner Castillo, a schoolteacher largely unknown to most Peruvians prior to the April first-round vote, garnered 43% of voting intentions in the poll, while Keiko Fujimori took 34%, according to pollster Ipsos Peru.
