ONEONTA, Ala. (AP) — Alabama's tough immigration law was supposed to create farm jobs for unemployed Americans, but few of them have shown any interest since the measure went into effect.Many of the Americans who have ventured out into the fields to pick crops have quit after a single day, telling farmers the work is too hard and not worth the pay.Politicians who support the law in Alabama insist more time must pass before it can be considered a failure. Yet early numbers from the governor's office show only nominal interest so far.Alabama passed its immigration law in June. It was immediately challenged as it has been in other states. Unlike other states' measures, Alabama's law has been left largely in place while challenges play out in court.
