AZ senator Steve Gallardo is starting the process. . .
Amid shouts from those on both sides of the issue, Sen. Steve Gallardo, D-Phoenix introduced legislation on Monday to repeal the controversial two-year-old immigration law.AZ Dems. pushing repeal of controversial SB 1070 law - East Valley Tribune: East Valley Local News
The article goes on to say that this specific bill is dead in the water, but it won't hurt Gallardo's career either way since he's in a district with a lot of Latinos, which means he'll fare better than the state senator (Russel Pearce) who wrote the original bill was immediately fired for it
Furthermore, even if that legislation gets canned, another bill will be drafted to repeal it, effectively rendering any SCOTUS decision moot.
Of course, a lot of conservatives likely don't believe that such a bill will be repealed so easily, but, alas, it reflects a basic ignorance about how politics works. . .
There's a general principle of politics that holds that the more conservative a state/municipality/govt. is, the greater the influence of businesses in that state over the laws. IN theory, an ultra-conservative state (i. e. AZ), then, is a plutocracy.
In a plutocracy, businesses ultimately write all the laws, using pols merely as a front to create the illusion of democracy--in practice this translates to using financial influence to oust pols that compromise their business interests.
And since AZ businesses don't like SB 1070 (since it impedes their ability to hire or work with undocumented laborers or entrepreneurs), they will ensure that any pol that defends its presence will be ousted just like Russel Pearce.
So Gallardo is just playing politics--he knows that even if his bill doesn't succeed, he'll get re-elected both due to Latino support and business support because he stood up for it.
But every other pol in AZ knows they will inevitably have to support its repeal if they value their jobs
