It’s one thing to tweet “boycott arizona” and another to make it happen.

For those of you who want to make it happen: Don’t book a flight on U.S. Airways, get a domain name through Go Daddy or rent a U-Haul truck.

So far, the first real pinch to Arizona’s economy has come from six canceled conferences. The state’s lost between $5,000 for the smaller groups and $45,000 for the larger ones. The Immigration Lawyers Association was one, nixing their meeting scheduled for later this year despite a reported $92,000 cancellation fee.

Everything else remains to be seen.

Yes, Mexico’s President Felipe Calderón has said he’s pissed off about the new anti-immigrant law and he will do something. You know, someday. Soon. And yes, San Francisco mayor Gavin Newsom has barred city officials from traveling to Arizona on business, except for work related to policing and public health, but the impact of that is yet to be seen and he doesn’t know what he can do about city contracts with Arizona businesses. He’s formed a task force to find out. Ditto for the city’s Board of Supervisors and Los Angeles politicans.

All of which means what we’ve always known: it’s up to people on the ground to make it happen.
