...an excerpt from a Yahoo news article:

Clinton headed to California Tuesday to accept the backing of the United Farm Workers Union. Founded by famed labor activist Cesar Chavez, the union represents a heavily Hispanic work force. Clinton won Nevada's presidential caucuses Saturday in part because of a strong showing among Hispanic voters — a central part of her strategy to win several states holding contests Feb. 5, including California, Arizona and New Mexico.

Of course, they use the term, "heavily Hispanic" without the word "illegal" but you know what the deal is...I HOPE!
