The latest survey from Public Policy Polling shows declining support in Arizona for the state's anti-immigrant law, but supporters still outnumber opponents of the measure.
Almost four years after it passed, PPP found declining support for Senate Bill 1070. In October 2010, the left-leaning firm found voters favored the legislation by a 25-point margin — 60-35. Voters still support the measure, but only by an eight-point spread — 44-36.
The measure's popularity has declined with Democrats, Republicans and independents.
The survey also found:
• Republican U.S. Sen. John McCain is unpopular with Republicans, Democrats and independents and is, according to PPP, the least popular senator in the country.
Only 30 percent of Arizonans approve of McCain and 54 percent who disapprove. McCain trails in a hypothetical general election against Richard Carmona and Gabby Giffords. He would defeat former Gov. Janet Napolitano.
• In presidential polling, Hillary Clinton narrowly trails Jeb Bush in a hypothetical general election contest in the state. She leads Chris Christie, Rand Paul and Mike Huckabee. In the GOP primary field, Ted Cruz leads.
• Jeff Flake's poll numbers "went into the gutter last April after he voted against requiring background checks on all gun purchases and they haven't seen any improvement since."
• A majority of voters — 53 percent — support increasing the minimum wage to $10 an hour.
• Support for legalizing medical marijuana is at 67 percent. The state is more evenly divided on recreational marijuana use — 46 percent think marijuana should be legal and 48 percent think it should continue to be illegal.
