If there were any good ideas at this convention of mostly rich and mostly right-wing delegates about how to haul the country out of this mess that the G.O.P. has gotten it into, they were kept well hidden. Perhaps they were tucked away behind the more prominently displayed creationism and “just-say-no to global warming” documents.

It stretches the mind almost to the breaking point to think of John McCain as an agent of substantive change. He once believed that Phil Gramm was the most qualified person in the United States to be president. And he now believes that Sarah Palin is the most qualified to be vice president.

That is not the fault of Mr. Gramm or Ms. Palin. But it sure tells us a lot about the judgment of John McCain.

Mr. McCain is a warrior, a former fighter pilot, and it’s no secret that Americans have long been thrilled by the romantic Top Gun narrative of fighter pilots, those specialists in the realm of the dangerous and the reckless. But we’ve also seen what dangerous and reckless behavior in the White House can do to a nation.

Sarah Palin may someday become president, and for all we know she may be a great one. But she was not chosen as Mr. McCain’s running mate after long and careful consideration and consultation. The best evidence is that she was a somewhat impulsive choice. Voters would be well advised to proceed with caution.
