-a single state passes laws strongly affirming the federal ones, forcing illegals to leave the state for more "alien-friendly" ones, like CA and NY
- as other, more conservative states continue to pass laws like AZ, there will be mass illegal movements into regions of the country (northeast, wst coast, south florida) that are illegal sanctuaries
- the costs/burdens on the sanctuary areas will eventually become so overwhelming, that they will become hopelessly bankrupt, forcing the mass exodus of legal citizens to the conservative states, a process already underway due to the differential income taxes between the "red" and "blue" states
- the sanctuary areas will collapse due to the unsustainable social welfare levels provided to the illegals, and these areas will closely resemble non-functional, ungovernable African and Latin american banana republics.
Given the mass import of both illegal and legal hispanics into the US, this breakup would have taken say, 50 years - but the tragedy of the AZ decision - one I personally applaud - has only moved up the timetable by several decades.
