This is not a surprise.
I have seen two polls of legal Hispanics. In both, they opposed amnesty by about 2-to-1 (roughly 60/32). And, why not, they are legal, they are Americans!
There is, indeed, a lesson here for the GOP-e on how to claim a larger share of the Hispanic vote.
None of the legal, established Mexican Texans I know are for amnesty.
Where is the link to those polls?
