Peru is getting ripeish for its own Morales. Not much hope for it in any other direction. Alas, Humala is a moron.
Actually, Peru's been blessed w/ fairly reasonable government for quite some time. The economy's been hot (w/ 2009 - the only, natural, exception - but even then it didn't get into the negative GDP growth), inflation low, poverty and inequality diminishing, etc., etc. Both Toledo and, surprizingly, Garcia (in his second incarnation) have been quite decent presidents by any objective measure - except personal popularity, of course. All this would be gravely endangered by a Morales or an Humala.
Don't forget that Peru is not Bolivia - it's not a majority Amerindian country, for one. And it is quite a bit richer. It is also a lot more governable. And, even by Peruvian standards, its recent governments have been doing quite well.
