If they're illegals, then there's every cause to object to this.
Well, I thought about it in terms of those who visit the country on tourist visa's, student visa's and a whole host of other non citizens who are eligible for driver's license privileges. Maybe I should amend my POV, but if they show up at a DMV, and there is no way for the DMV to know their status...
If someone is here illegally, I would love to see them gone. I would like it to happen via attrition such as showing up at a DMV, and being found out, or traffic stops or any other of a number of ways. Unless I am missing something, an illegal with a legitimately procured driver's license hasn't had their illegal status benefited from the exchange.
