Evo Morales ought to be a strong tribune for the interests of all indigenous peoples throughout his country. But it's possible that he distinguishes between the interests of the populous Andean groups, Quechua and his own Aymara, and those of the more diffuse, less connected indigenous of the lowlands to the east -- and naturally, being a politician, prefers to support his own. That's unfortunate, and even unjust, but it's good democratic behavior, "good" in the sense of "efficient."
