Not quite, SB 1070 was about enforcing immigration, to counter this the court would have to declare that governors have no right to (a) declare invasion, (b) demand the Federal Government abide by Art 4, Sec 4 of the US Constitution, or (c) defend their states w/ the [State's] militia.

Also, Scalia wrote a good dissent, here, which I remember him mentioning something like the only sovereignty left after this decision was that of military/militia usage. [Sorry, I couldn't find the exact quote.]

Not quite..

Correct. Not quite, but close enough. Not to rain on your parade or anything, but with the current Regime we have in DC; I don’t foresee any State passing legislation as you suggest.

SB 1070 was wrongly decided anyway. I’d go right on enforcing it and make the justices come after me.
