NEW YORK - MAY 01: Hundreds of activists, supporters of illegal immigrants and members of the Latino community rally against a new Arizona law in Union Square on May Day on May 1, 2010 in New York City. Following the state of Arizona's passage of a new immigration law which requires individuals suspected of being illegal immigrants to show proof of legal residence when asked by law enforcement, immigration supporters have been protesting across the country. The law has become increasingly divisive, with Mexico's president issuing a travel warning to Mexican citizens in Arizona. Thousands of people are taking part in similar protests around the country on May Day, a traditional day of protest around the world. (Photo by Spencer Platt/Getty Images)
A new poll finds Californians are nearly evenly divided over Arizona's illegal immigration law.
The Field Poll released Friday says 49 percent of registered voters support it, while 45 percent are opposed.
Republicans strongly favor the law, which is facing several legal challenges. Democrats are heavily against it.
The poll finds that majorities of whites and blacks favor the law, while 71 percent of Hispanics object. Opinion in the Asian community varies by ethnic group.
The law requires police to question suspects about their immigration status if there is a "reasonable suspicion" the person is in the country illegally.
The telephone survey of 1,390 registered voters was conducted June 22 through July 5. It has a margin of error of plus or minus 2.8 percentage points.
