I don't have the all the links, but you can start with this guy......Kris Kobach (
http://en.wikipedia.org/wiki/Kris_Kobach ) then follow up with FAIR (mentioned above) and The Pioneer Fund and guess who .......the John Birch Society.
The fun thing about Kobach is he wrote the AZ law and a similiar law in OK that was tossed out and declared unconstitutional by federal courts. The AZ is unconstitutional based on the 14 amendment.
Another fun thing is the AZ law requires police officers be trained in how to implement the new law and guess who that rat bastard Arpaio is going to use to train his officers at 300 bucks an hour.
There is also another little clause in that law that allows citizens of AZ to file suit against any law enforcement agency they think is not enforcing the law. The law is apparently set up so Kobach can represent either side in the suit.....guess he can't decide which is more important: racism or money...
reading the law and doing some research is kinda interesting sometimes......
