How McCain was embarrassed by his claiming "the fundamentals of our economy are strong" is delicious.
His several attempts to try to justify this gaffe and to make it sounded different that it does are a real beautiful exercise of trial and error in a deployment of a strategy.
Finally, he succeeded to connect it to a more favorable matter, saying the "fundamentals" are the workers themselves. This point must have been suggested by a clever economic adviser. But isn't it too late to be convincing?
