The New York Times covers the McCain/Palin rally at the Pima County Fairgrounds:

Ms. Palin, Alaska’s former governor, is the latest in a parade of prominent Republicans coming to Mr. McCain’s aid in Arizona. In recent weeks, he has stood side by side with Senator Scott Brown of Massachusetts and Mitt Romney, the former Republican presidential rival. And Jeb Bush has endorsed his candidacy from afar.

But it is an open question what effect the endorsements will have in a state where Mr. McCain is well known and suspicion is running far deeper than during his previous races for re-election. Mr. Hayworth, who has drawn the support of several Tea Party followers and other conservative activists, welcomed Ms. Palin to Arizona but doubted that her seal of approval for Mr. McCain would mean much to voters.

“What we’re seeing from the governor is a very understandable example of gratitude,” Mr. Hayworth said. “After all, it was John who really gave her an entree to the national stage.”

Throughout their presidential campaign, Mr. McCain and Ms. Palin often drew differing strains of Republican voters to their rallies. When the two merged on Friday, the differences were even more pronounced. In six interviews with people in the crowd, five said that they had come to see Ms. Palin and were uncertain about Mr. McCain.

“I love Sarah! I wish she was the president now,” said Shirley Daniel, 65, a Tucson nurse. “I’m not as much of a supporter of John. He’s a good man, but I think his time has come. I think Hayworth would be a better candidate for the Senate.”
