First, it was tomatoes. Now potatoes. Alabama's tough new immigration law, touted the worst in the country, has worked mighty fast. It quickly drove experienced Hispanic workers out, leaving crops rotting in the fields, few new workers able or willing to do the backbreaking work, and many farmers losing their farms. At one, the law's GOP sponsor was invited to pick and haul one bucket of potatoes. He declined. Some great rants on the subject here.
