Don't depend on that. There will always be demagogues who fasten on discontent. Wouldn't surprise me if a Chavez type pol shows himself in districts that run 90% Mexican. So far La Raza has not made a dent, but that could change.
La Raza types have positions of power in the California legislature and one is mayor of Los Angeles.
I agree completely, but because the reason for these folks being here in the first place (employer/politician greed)isn't being addresses I see both happening simultaneously - a huge radicalized latino voting block continually fed by an endless flow of cheap labor.
