Andrew McCarthy, at National Review Online, notes that in a world of increasingly complex, unclear and voluminous laws, perhaps the federal government's biggest problem with Arizona's new immigration law is that it is too clear:

"Maybe that’s the Obama administration’s problem with Arizona’s new law: It is too short (16 pages), too clear, and too reflective of the popular will. Unlike the social scientists in Nancy Pelosi’s federal laboratory, state lawmakers didn’t need to pass the law first in order to find out what was in it. Essentially, it criminalizes(as a state misdemeanor) something that is already illegal (namely,being present in the United States in violation of federal law,and it directs law-enforcement officers to, yes, enforce the law.Democrats and their media echo-chamber regard this as radical; for most of us, it is what’s known as common sense."
