I think the ID question is crucial to dealing with this. However, one of the things that everybody keeps overlooking is that, with all the ID in the world at the Federal level, if the STATES and MUNICIPALITIES prevent the enforcement of Federal law by preventing ID checking, etc., the Federal policies will not work. You are aware, I assume, that there are many cities that prohibit their police forces, healthcare workers and schools from either asking for real ID or checking it, and from reporting immigration violators when they are found?
Theoretically, illegal immigrants are already supposed to be excluded from receiving certain benefits (such as Federally funded welfare programs). But the states and cities that handle the distribution of these funds prevent this law from taking effect by simply refusing to check the status of applicants for benefits.
The Dem governments at those levels do this to build a pool of illegal voters, and preventing the enforcement of ID laws also enables them to get these people into the voting booths.
So I think that it would be more accurate to say that unless the state and local government carry out their responsibilities, the Federal laws will remain unenforceable and this situation will continue.
My point is that nothing is tamper proof.
Now, I'd like a tamper proof president and congress.
