Pure genius, I tell you. With an estimated half a million illegal immigrants residing in Arizona according to the Pew Hispanic Center, questions are being raised about what this means for the United States and its national identity. But according to Newsweek contributing editor Eleanor Clift, it's a "happy" thing with lots of upside.

On the May 2 airing of "The McLaughlin Group," show moderator John McLaughlin raised the issue about the country's identity, particularly when it comes to English as the United States' primary language.

"The bedrock is national identity," McLaughlin said. "If the national identity suffers by reason of multiple languages, then the bedrock of our society, which is our identity, being an American is an American. English preserves that."
