This can only be good news for John McCain.
Adding that McCain's latest line - "fundamentals of economy are strong" = "don't pick on the workers" - makes as much sense as "We've already won in Iraq so we have to stay there until we win". Obviously, employees are still working hard at their jobs, people still need stuff, and all that other day-to-day economics stuff still goes on. When billions of dollars in value disappears in a day, threatening even more losses in the days ahead, however, that kind of empty platitude doesn't mean much. I think people should be reminded that Herbert Hoover tried the same line over and over again, and look where he ended up.
