Name one? OK. George Soros, who has already said publicly that he would spend his whole fortune if he could be certain of the defeat of Mr. Bush.
And, just btw, Mr. Soros does indeed know how to manipulate mkts, although manipulating both NYSE and NASDAQ would probably be a bit too much for even HIS pocketbook.
