BTW, one main way this new law is almost certain to be implemented this fall is at polling places.

People will be hired - some perhaps wearing official-looking uniforms - to harrass "Hispanic-looking" voters at the polls, threatening them that IF they actually vote and then cannot produce a passport or other proof of citizenship (a voter registration card won't be accepted), they will be arrested.   

That will be enough to deter thousands of US citizens of Hispanic descent from voting.

Mission accomplished.
