ARIZONA: It's never good when your kick-off ad features your wife lamenting negative ads and saying you're "not perfect." But that's the backdrop of J.D. Hayworth's first ad after getting pummeled on air and in the press by McCain's campaign. "Tired of John McCain's negative ads? So am I," Hayworth's wife, Mary, says right before turning off her flat-screen TV. "I'm Mary Hayworth, and John McCain is hiding his record behind false attacks on my husband. John McCain has sold out the people of Arizona on immigration, bailouts and tax increases. Now, John McCain has embraced character assassination to keep his job. John McCain should be ashamed. J.D.'s not perfect but he is a principled conservative."

Politico's Jonathan Martin wrote yesterday, "To inoculate himself [McCain's] run from the, yes, maverick image he nurtured for years and perhaps done lasting damage to his brand. But it may have won him six more years in the Senate."

CALIFORNIA: A new Field Poll shows Barbara Boxer leading Carly Fiorina by just three points, 47%-44%, in the state’s Senate contest. “At the same time, her job approval rating is among the lowest that Field has measured for her since she was first elected to the Senate in 1992: 43 percent of registered voters disapprove of her performance while 42 percent approve. Among likely voters, 48 percent disapprove and 42 percent approve,” the San Francisco Chronicle reports. “While voters' responses to a pollster in July may change by the time they vote in November, the new poll shows that whether voters love or hate her, 93 percent hold an opinion about Boxer. ‘She is vulnerable,’ Field Poll director Mark DiCamillo said. ‘This is very ominous for her.’”

NEVADA: "Sen. Harry Reid opposes Arizona's new border law and has proposed an alternative in Congress. But he declined Wednesday to take a stand on the Obama's administration's lawsuit against the state," The Las Vegas Journal-Review reports. "Reid, D-Nev., declined to offer support or to distance himself from the Justice Department's challenge of the Arizona law as unconstitutional. 'That's the administration's decision,' Reid spokesman Jon Summers said when asked for Reid's views on the lawsuit and whether he agreed with it." And: "Democratic Rep. Dina Titus also questioned the suit, saying it would do little to solve the root problems of immigration." Titus is sure to be in a tough reelection fight.
