It is sad -- Peru should be a leader in progressive alternatives in Lat Am. But even in the wide field of the first round of voting there was barely even a non-disgusting candidate. The utter disarray really is a major example of the importance of having theoretical/intellectual leadership (or rather the disaster of NOT having it). Internationally as well as nationally.
Garcia's APRA is a direct product of the confusion and vacuum in Lat Am caused by the interregnum between the 2nd and 3rd Internationals when the Party was founded by the socialist movement (briefly with Mariategui as a member). In that flux APRA was quickly captured by elements that are simply a bad caricature and the Peruvian left never recovered. APRA's early monopoly in the industrial and plantation areas of the north -- the most fertile political terrain - has long smothered more promising movements.
That also left the South with its indigenous rural areas cut off from political links to industrial or plantation workers. Their frustration - in a political vacuum - eventually lead to Sendero (whose base was in the indigenous South) and a second round of disasters for the left. Garcia's opponent, Humala, is from this region and has inherited this politically devastated social group as his base. Since launching his campaign Humala has affected links to Chavez and Morales but his lifelong past was as a fanatic devotee of an ultranationalist, racialist, sect founded by his father along with a military career "in close proximity" to human rights crimes.
But you can see the point: in a serious way a majority of Peruvians ARE voting for a pink tide...but that is not what the candidates represent.
