Okay, first off, it's not "undocumented migrants," it's illegal aliens. The Leftists need to stop trying to pass this Orwellian newspeak off as reality.
Secondly, legal immigrants have no love of illegal immigrants. And considering that simple fact, I sincerely doubt that legal immigrants who can vote will do any "punishing" of Bush at the polls.
This whole thing stinks of another Leftist hit piece in which they're trying to forward their socialist fiction as fact.
You make some good points, but while the euphemism 'undocumented immigrant/worker' was a creation of the Left, it is now becoming more widespread in its use by those allegedly on the Right. Bush uses it. GOP Senators use it. The WSJouranl uses it.
Among the media, it seems to be about 50/50 now between some variation on the 'undocumented' term verus 'illegal immigrant.' 'Illegal alien' -- the best and most accurate description -- seems to be dying out.
You're right that legal immigrants should be just as or even more upset about illegal immigration as anyone else seeing as how they must often compete with them for work.
But Kerry/Edwards will easily win the legal immigrant vote this year. Gore blew Bush away with Hispanics by something like 62-35, and right now Bush is polling even worse among them. Bush also lost the Asian vote.
Demography is moving towards the Left/Dems. I've read things by people like Michael Barone who say otherwise, but I can't buy any of his arguments.
