The US Supreme Court has upheld Arizona's Employer Sanctions law. Look for the mainstream media to try to downplay the story by claiming that this is somehow a "narrow" victory. It's an epic victory. Illegal immigration is an economic issue. If someone who makes $10 a day south of the border can make $10 an hour north of theborder then it's worth a lot of money and effort to cross that border. Removing the economic incentive is a much more effective deterrent than the highest wall or deepest moat.
The media have used three strategies to discredit the Employer Sanctions law. First they argued that the law was so broad that "mistakes" could lead to businesses losing their licenses. This is obviously false because the law calls for "knowing" violation. The media then flipped strategies and argued that the law was too narrow--"knowing" violations are so hard to prove the that law couldn't be enforced.
The final argument was that the law was unconstitutional. Now that argument is gone as well.
The Employer Sanctions law isn't as flashy or controversial as SB 1070, but it's just as effective--perhaps more so. This is an epic victory.
