Earlier today, the Supreme Court struck down an Arizona law that would have required voters to show proof of citizenship to register to vote. Judge Andrew Napolitano reacted to the move on Varney & Co.

He explained that the Supreme Court ruled that when Congress enacted the National Voter Registration Act, it set standards that the states must follow. The question became whether the states could add to those standards. “Arizona attempted to add to them, the Supreme Court said you can’t do that,” Napolitano said.

Napolitano then took on reports of New York City Mayor Michael Bloomberg’s plan to announce a mandatory food composting program. According to Napolitano, this is “the nanny state gone crazy.”

“This is more for the convenience and money-saving of the sanitation department. This has nothing whatsoever to do with the environment,” Napolitano said.

When asked why Bloomberg is trying to enact such a plan, the judge said, “Because he likes to tell people how to live and he thinks he has a better model for urban living than our freedom of choice.”

It's not the first time Napolitano has had some harsh words for Bloomberg, recently referring to him as a "dictator."
