The idea that Americans want leaders who have none of those things  who are so blindly certain of what Ms. Palin calls “the mission” that they won’t even pause for reflection  shows a contempt for voters and raises frightening questions about how Mr. McCain and Ms. Palin plan to run this country.

One of the many bizarre moments in the questioning by ABC News’s Charles Gibson was when Ms. Palin, the governor of Alaska, excused her lack of international experience by sneering that Americans don’t want “somebody’s big fat résumé maybe that shows decades and decades in that Washington establishment where, yes, they’ve had opportunities to meet heads of state.”

We know we were all supposed to think of Joe Biden. But it sure sounded like a good description of Mr. McCain. Those decades of experience earned the Arizona senator the admiration of people in both parties. They are why he was our preferred candidate in the Republican primaries.

The interviews made clear why Americans should worry about Ms. Palin’s thin résumé and lack of experience. Consider her befuddlement when Mr. Gibson referred to President Bush’s “doctrine” and her remark about having insight into Russia because she can see it from her state.

But that is not what troubled us most about her remarks  and, remember, if they were scripted, that just means that they reflect Mr. McCain’s views all the more closely. Rather, it was the sense that thoughtfulness, knowledge and experience are handicaps for a president in a world populated by Al Qaeda terrorists, a rising China, epidemics of AIDS, poverty and fratricidal war in the developing world and deep economic distress at home.
