WSJ story about a small town in Nebraska that's coming apart at the seams over a proposed, AZ-like tough law on illegal immigrants. The town (Fremont) is almost exclusively European, with most residents of Swedish and German background. A substantial meatpacking company presence has--unsurprisingly--boosted the Hispanic presence recently (around 1k out of 25k total population), leading to the tension. Naturally, such a potentially divisive law attracts a lot of outside players joining the fight.
I was just more attracted to the chart, which details the biggest increases of foreign-born residents in states with more than 100k foreign-born already. I mean, look at the spread that includes the mid-Atlantic/south with the two Carolinas and GA, New England with RI, the plains (NE), the north (WI), Appalachia (KY), and the mountainous West (CO). This is hardly just a SW America issue, thus the rule-set clash currently being played out in Arizona is but a harbinger of a large struggle to come.
My point: welcome the experimentation by states. Some will bad and some will be good, but the churn will help us collectively find the right mix over time.
