As of about half an hour ago, 83.87 percent of the votes have been counted and it seems more and more certain that Alan García will make it to the second round. He currently has a 0.9 percent lead over Lourdes.
Unfortunately the official ONPE site is always a few hours behind. Though it doesn’t matter much because they are currently counting at a rate of 3% a day (or so it seems).
Update: The Peru Election weblog reports that ONPE (the official electoral office) has just started counting the votes aborad. About three percent of the Peruviants vote from abroad, so this could actually alter the result in favour of Lourdes. The foreigners are estimated to vote more in favor of Lourdes while the rural areas (which is the main part of the votes that have not been counted yet) generally vote for Alan and Humala. The suspense will probably only terminate when 100 percent of the votes have been counted.
