A growing body of polls suggest many voters support the Arizona law.

From The New York Times:

Arizona’s new measure, which requires that the police check the documents of anyone they stop or detain whom they suspect of being in the country illegally, has forced politicians far and wide to take a stance.

The decision on whether to support or oppose the law can have almost immediate political consequences. The latest evidence may be Meg Whitman’s declining fortunes.

For months, Ms. Whitman, the former chief executive of eBay, enjoyed a substantial lead over her principal rival for the Republican nomination for governor of California, Steve Poizner. But in recent weeks, she has seen her advantage slip significantly, in no small part because Mr. Poizner has hammered her on her opposition to the Arizona law.

Finding herself increasingly on the defensive on the issue, Ms. Whitman even proclaims in a new advertisement: “I’m 100 percent against amnesty for illegal immigrants. Period.”

Nonetheless, a poll released Wednesday by the Public Policy Institute of California showed her advantage falling 23 percentage points since March, down to 38 percent versus 29 for Mr. Poizner.

In Florida . . . for instance, Attorney General Bill McCollum, who is running for governor, now says he approves of the law, though he called it “far out” two weeks ago; Marco Rubio, the state’s Republican Senate nominee, has also shifted his stance.
