> I like to joke that I have more documenting showing my legal right to be in the US than my wife's grandmother.
You are mistaken. Your wife's grandmother ( assuming she is native born ), even though she may not have "papers", is undeportable. Whereas you have legal documents showing that you are not a a native born citizen. You are someone that we can deport. Naturalized citizens can be deported from the US. A native born american cannot.
> Americans seem quite dead set against a national ID scheme (and associated database).
There really is no need. Most americans have state IDs and if they want to travel abroad, US passports.
> ICE, interior immigration checkpoints, and other initiatives seem to be on the rise.
But for american born citizens, that isn't a worry. It's a worry for immigrants - legal or illegal. Not for native born citizens.
