After seeing widespread debate over this issue yesterday due to Chavez's intervention on behalf of Humala, I think it is time to look at this objectively:
http://news.bbc.co.uk/2/hi/business/5007556.stmGarcia is center-left. Humala is just plain old left. Both oppose the latest free trade agreement with the US, both are in favor of fiscal responsibility, and both want to increase social spending. There actually is no major ideological clash. Humala wants to nationalize companies while Garcia wants to make them pay higher royalties and taxes.
My friends, this debate is a false one. Not all countries automatically have left vs. right elections. In this case it is left vs. farther left. Before simply taking the media or Chavez's word for it, look at it closely and realize that it really is a no lose situation.
