Drivers license = license to drive = knowledge and ability to drive (one hopes). I find it hard to believe that any substantial percentage of "Hispanics" (whatever that word means) thinks undocumented migrants should be deprived of this. I live in New Mexico, the state with the largest percentage of "Hispanic" citizens and individuals of Spanish heritage, and the documentation requirement for a New Mexico drivers license reads as follows:

You will need to provide one (1) proof of identification number; one (1) proof of identity and two (2) proofs or New Mexico residency. If you are eligible for a Social Security number (SSN) your proof of identification number will be your Social Security card or a verification document from Social Security confirming your SSN. If you are not eligible for a Social Security card, you will be required to provide a valid passport issued by your country of citizenship; a Matricula Consular issued after February 1, 2005 by the Mexican Consulate in Albuquerque or El Paso; or an individual tax identification number (ITIN) card or the letter from the IRS issuing your ITIN.

Any Mexican citizen residing outside of Mexico can obtain a Matricula Consular, regardless of his or her legal status.
