Speaking at a town hall meeting at Morningside College in Sioux City, Iowa yesterday, Republican presidential candidate Mitt Romney backed a national ID system and government pre-approval of all new hires in the country. It’s a stunning amount of power he wants the federal government to have.

Addressing a question about illegal immigration (starting at 30:40 in this video) he said:

You’ve got to crack down on employers that hire people that are illegal, and that means you have to have a system that identifies who’s here legally, with a biometric card that has: this is the person, they’re allowed to work here. You say to an employer, you look at that card, you swipe it in your computer, you type in the number, it instantly tells you whether they’re legal or not.

He’s describing an expanded E-Verify system, and the biometric national identity system that has been proposed for it. That system would not only be used for controlling employment, of course. Like the Social Security number did when it caught mission creep, the national ID Romney talks about would come to be used to control access to housing, to financial services and credit, gun ownership, health care and medicine, the list goes on and on.

It’s technically possible to have a biometric card that solely indicates one’s qualification to work under federal law, but as I wrote in my paper, “Franz Kafka’s Solution to Illegal Immigration,” there is almost no chance that the government would limit itself this way. E-Verify requires a national identity system, and Mitt Romney wants that national identity system.
