One of the less examined aspects of recent debates over immigration is the activism of Latin American governments, which transcends ideology. Mexico is the most obvious case, and I've written about Felipe Calderón's statements before, but it is evident across the region. It may well be one of the few things that governments as disparate as Bolivia and Colombia can agree upon. It should be a topic of conversation for regional organizations.
