Presumptive Republican presidential nominee Mitt Romney leads President Obama in Arizona, according to a Magellan strategies poll released Thursday.
Romney leads Obama 52 percent to 43, according to the poll. That’s the same margin by which Sen. John McCain (R-Ariz.) won his home state in 2008, when he defeated Obama 54 to 45.
The Magellan poll differs from other polling conducted in late April that showed Arizona, a historically Republican state, to be a toss-up. Obama led Romney 42 percent to 40 in a Rocky Mountain poll from April 25, while a Merrill-Morrison Institute poll released earlier that week showed Romney with the 2-point advantage.
But the national edge with Hispanics hasn't carried over to Arizona, according to Magellan. The poll found that Obama trails Romney among Latinos in Arizona, 52 percent to 42.
Arizona’s controversial immigration law, which underwent oral arguments before the Supreme Court last week, could be a factor in the general election.
A Public Policy Polling survey also released last month showed nearly six in 10 Hispanic voters in the state said Romney's support for the law made them less likely to vote for him.
The survey was conducted between April 30 and May 2, and has a margin of error of 3.25 percent.
