Huge concern has been placed upon the access of drivers licenses and the "motor voter" laws made by Clinton. No one checks citizenship when they hit the "ok".
I am still not sure why non-citizens are given a drivers license without the pre-requisite drivers education courses we all had to take in high school.
I am not saying anything like toss em out. I am saying .. by all means make it easier to become a citizen. Have your background checked and sign in like my grandparents did at Ellis Island.
