DACA beneficiaries are being singled out negatively by Brewer because they're high profile. In other word, it's a strategic political move rather than a logical attempt at making policy. Worse, it could very well be a product of her petty squabble with Obama. Her argument about 'status' doesn't hold water because the CFR clearly defines many other types of aliens who qualify for EAD without having status. To make an analogy, it's like saying "we don't give benefits to Mexicans because they're Hispanics" while giving benefits to Guatemalans, Venezuelans, Colombians, Peruvians, etc.

Ok, so AZ wants to do something about illegal immigration by targeting all aliens without status. Well then go ahead and refuse to accept EAD as primary identification document! They will deny DL to asylum seekers, refugees, and even Cubans who haven't received green cards. Let's see how that works out for them at the Supreme Court. I think the only reason nobody bothers with a lawsuit yet is due to all the talks about Obama and Republicans wanting to tackle CIR next year. These lawsuits can take years, and people don't want to spend the legal effort if there's a chance that it will be moot in several months.
