their arguments from the Supremacy Clause and the Constitutionally-mandated federal jurisdiction over immigration are valid and compelling.

I found those arguments neither valid nor compelling. The Federal Government has already passed laws requiring local law enforcement to cooperate with the Feds in enforcing immigration laws much like the Arizona law requires. States like New York that do not cooperate are actually in violation of Federal Law. That Bozo and his AG don't prosecute does not make the law invalid.

So?

The Federal Government has already passed laws requiring local law enforcement to cooperate with the Feds in enforcing immigration laws much like the Arizona law requires.

It doesn't work both ways, though ... and that's the essence of the decision.

We agree that the Feds have failed to properly deal with illegal immigration. The question is how best to address that fact.

Arizona's approach was never going to pass muster in the courts.
