"As the stock markets continue to fall and economic indicators point toward a recession, Democratic politicians are reviving charges that President George W. Bush has been "talking down" the economy. My first reaction to such charges, other than to dismiss them as nonsense, is to wonder whether or not politicians ought to be accusing their rivals of having superhuman powers. Perhaps the next charge will be an accusation that Bush is using witchcraft to bring down the Dow.

However, with the "talking down" charges certain to be leveled again and again as the economy tanks, perhaps it is time to explain why politicians—not to mention Federal Reserve chairmen—cannot cause a recession with mere words. I do not fear what politicians say, but I greatly fear what they can do."
