So, federal government, what do you do when a state goes over your head and passes some bill that intimately impacts their own economy, police, etc.? Why, of course, the only logical thing is to pass your own bill so you can reassert your superiority! Right?
Now, I'll admit. I have some problems with the Arizona immigration law. What I don't have a problem with is a state taking care of problems in its own sphere of influence. For instance...state boundaries. That's their job. No harm, no foul.
Of course, in today's climate of federal-government-first-cuz-we're-awesome, it isn't hard to find beauties like this: "Mr. Obama said it was vital that Congress address the immigration issue, lest more state measures like the tough new law in Arizona sprout up."
....Oh no. Constitution forbid the states actually, like...exercise their power! That would be just way unconstitutional....
Oh. Wait. What's this you say? Tenth Amendment?
"The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people."
Huh. Fancy that.
Now, I don't see anything in the Constitution about immigration. Except this:
"The Migration or Importation of such Persons as any of the States now existing shall think proper to admit, shall not be prohibited by the Congress prior to the Year one thousand eight hundred and eight..."
And this in the powers of Congress:
"To establish an uniform Rule of Naturalization..."
Now in the first- the States decide who comes in, and when. Hence, Arizona's law is arguably not unconstitutional.
The second sets Congress' role in the immigration/nationalization process. Which is the last part. Congress decides the process whereby someone becomes an American citizen. Don't you love it how the Founders balanced everything out...and how everybody has to work together?
Sorry, Congress. Immigration is not Constitutionally your job.
Get over it.
