while i can understand any concern you would have if this were happening with regards to U.S. politics, i confess i don't understand the concern for mexican politics.
on the surface (and i'm not naive enough to think that this is a pure, altruistic attempt to make sure mexicans "citizens" are given adequate and fair representation even when living abroad) it sounds like the [red]elected representatives to the Mexican lower house from their respective regions in Aztlan and from countries where significant number of Mexicans reside[/red] will be Mexicans and not citizens/subjects of whatever foreign country the Mexicans are living in.
i guess i don't see a problem with this kind of representation.
