Actually it's the busienss people in Alabama who are complaining, because the bill is killing them. The latest incident really brings it into focus.
"On Nov. 16, a European businessman paying a visit to his company’s manufacturing plant near Tuscaloosa, Alabama, was pulled over for driving a rental car without a tag.
The police officer asked the man for his license, but the only paperwork he had with him was a German I.D. card. Anywhere else in the nation, the cop might have issued the man a citation. Not in Alabama, where a strict new law requires police to look into the immigration status of people detained for routine traffic violations. Because the man couldn’t prove he had the right to be in the U.S., he was arrested and hauled off to the police station.
The businessman turned out to be an executive with Mercedes-Benz, one of Alabama’s prized manufacturers, Bloomberg Businessweek reports in its Nov. 28 issue. The Mercedes plant employs 3,400 people, and the company’s much-heralded decision in 1993 to build cars in the state encouraged Hyundai, Honda, and Toyota to follow.
Mercedes has downplayed the incident, calling it “unfortunate” and refusing further comment. Yet word of the arrest spread quickly through the state, amplifying a growing sentiment among many politicians, business owners and citizens that the immigration law, intended to drive off undocumented workers and free up jobs for the unemployed, is too strict and damages Alabama’s reputation as a place to do business."

What the article didn't mention is that Mercedes has created over 40,000 jobs in the state since they made it its US manufacturing hub in the early 90s. At the time they were quite hesitant to choose Alabama because of German sensitivity to racial issues and Alabama's less than stellar history. It is probably no coincidence that the confederate flag was taken down from the state capital the year that Mercedes started doing business there.
