Not long ago John McCain was almost boasting that he knew little about economics. That kind of candor, a distinctive McCain trait, is likable but has its limits. His days of making jokes about his ignorance appear to be over. Worries about the economy began to dominate public opinion even before the current slowdown was properly under way.

Why confine the choice to eliminating the Bush tax cuts entirely or preserving them as they stand?

Between now and November, those worries will only mount: The faltering economy is likely to get worse before it gets better. McCain is going to need an economic program, and he had better get used to talking about this subject as though it matters.
