And the divide is largely racial:
In the poll, 61 percent say they favor Arizona’s new anti-illegal immigration law, which would require local and state law enforcement officers to question people about their immigration status if they have reason to suspect a person is in the country illegally. The law would also make it a crime to lack the proper registration documents.But there’s a divide among white and Latino respondents: 70 percent of whites support the law, versus just 31 percent of Latinos. In fact, 58 percent of Latinos say they strongly oppose it. That’s not the only chasm between White and Latino America. While 68 percent of Latinos believe that immigration strengthens the United States, just 43 percent of whites think that.
