A Fox News/Opinion Dynamics survey released Thursday indicated 72 percent of respondents believe the federal government is not enforcing existing laws against illegal entry to the country, while only 21 percent said the government is enforcing the law.
Fifty percent of respondents said they favor Arizona's tough new immigration law, which requires law enforcement officers to request proof of citizenship from persons they suspect are in the country illegally. Only 31 percent of respondents oppose Arizona's law, while 19 percent said they were unsure.
The poll surveyed 900 registered voters July 27-28. The margin of error is 3 percentage points.
