This is probably the worse arguement to be made in favor of Bernanke:

Geithner suggested that the market would see a failed Bernanke confirmation as "very troubling," but claimed that he was "very confident" Bernanke would receive enough Senate votes to win a second term.

"The markets would view this as very troubling thing for the economy as the whole," Geithner said. "I don't think they should be uncertain. I think they can be confident because we're very confident."

It's just silly to make this arguement. The markets will probably react negatively short-term, but that's already in thw works. After a 78% rally from the lows, of course the markets need to correct. And they will.

But more fundamentally, ask your self this: what have the markets done for you lately? Probably not a damn thing. The only people benfiting from a rising market these days are the bankers. The markets are not the economy. And the real economy, not the one on Wall Street, is still in the tank.
