A driver's license is proof, one hopes, that the possessor knows how to physically operate a motor vehicle and has passed a very simple written test on driving regulations. It is not, and should never be, proof of citizenship or the legal right to be in the US. There are other documents for that. If supporting granting driver's licenses to illegal immigrants is a bad thing, than one assumes that the opponents of this proposal are ok with them being out on the road unlicensed? Having been rear-ended a couple of years ago by a lady who had no license, no vehicle registration, no proof of insurance and who no habla ingles, somehow I think that is a bad idea.
