In 2006, U.S. Rep. Jared Polis - Democrat of Colorado - won one of Mexico's top awards for foreigners due to his strong support for illegal immigration. To this day he continues to demonstrate that the Mexican government is great at picking those on their side. Speaking to The Politico (link), he said of the recently-signed Arizona immigration law:

"It is absolutely reminiscent of second class status of Jews in Germany prior to World War II when they had to have their papers with them at all times and were subject to routine inspections at the suspicion of being Jewish... ...I fear that Arizona is headed for a police state and it really underscores the need for immigration reform at the federal level to fix our system

Polis was careful to point out he was not comparing the law to the Holocaust but rather to the period before the war when Jews were required to carry papers and identify themselves publicly.

"I think it’s a very fair comparison and I hope that we’re not headed on the same trajectory that Nazi Germany was,” Polis said. “But this was a very recent experience for Jewish Americans and Jews worldwide and it’s something that when we see similarities we start ringing alarm bells."

Legal immigrants are already required by federal law to carry a green card or similar showing legal permission to be here; does Polis think long-established federal law is akin to Nazi Germany? That might be a good thing to ask him.
