This is perhaps the best, most meaningful solution to the problem of the People's Republik of Kalifornia. As a resident of the Los Angeles area, I would love nothing more than to have this state liberated by pro-freedom forces.
Contrary to popular opinion, not all Californians are tofu-sucking, granola-munching, Birkenstock Liberals. Many of us are staunch conservatives who remain in this state because of our work in the military and high-tech fields.
All told, if there must be a boycott, I would recommend a higher granularity of boycott so that it will affect only those cities that have consistently supported rabid anti-American policies.
Berkeley comes immediately to mind.
