On Tuesday, Mr. Bush’s role became much clearer when he held his first event for Mr. McCain. He will show up to raise money (thank you very much), and he will say and do as little as possible, at least in public view. A large, and presumably public, fund-raiser at the Convention Center here was hastily rescheduled for the seclusion of a private home on Tuesday evening in Scottsdale. Mr. McCain’s main public appearance of the day was a foreign policy speech in Denver, not the visit by the president to his home state....

The senator and Mr. Bush avoided any meaningful public appearance together, planning just the briefest of photo opportunities at Phoenix Sky Harbor International Airport in the evening. Mr. McCain and Mr. Bush emerged from opposite sides of their limousine at the airport. They shook hands and waved, and Mr. Bush got on his plane without making a public statement. The joint appearance lasted less than a minute.

 But I'm sure it felt like much longer.
