I guess I've never understood this issue. Clinton's motor-voter law required the DMV to provide voter registration application forms with drivers license application forms. You don't need the latter to apply to vote; you just have to provide name/birthdate/address and sign an oath that you're a citizen.
Obviously illegal aliens should be deported, not given drivers licenses that establish (illegal) residency and help them pretend to be legally here. But, how do the licenses help illegal aliens vote in CA, where pollworkers do not check voters' ID?
