Just eleven weeks before the vote and here's the latest opinion poll on Peru's presidential election, run by IMA Estudios de Marketing (decent enough pollster) for national newsparer La Republica on a national urban/rural level with a goodly sized sample and a margin of error of +/- 2.3%:
The headline is that Toledo is stretching his lead (which probably explains the recent negative attacks on him from all sides) and it seems he has taken up most of the percentage points attributed to Mercedes Araoz before she dropped out of the race recently (APRA implosion). Castañeda and Keiko are still duking it out to see who gets the all important 2nd spot and makes it to the near-inevitable run-off and both their polling numbers have remained static in recent weeks, while Ollanta Humala has made a little progress up to 12.1% from recent scores of 10% and 11%. PPK is still getting nowhere and the rest, for all practical purposes, don't matter.
IKN prediction: This campaign is about to get very dirty.
