In an Uncertain World: Tough Choices From Wall Street to Washington By Robert Rubin and Jacob Weisberg, Random House, 448 pages, $35.00
If a Democratic president gets to replace Federal Reserve Chairman Alan Greenspan when the latter's term is up in 2006, Bob Rubin is the odds-on favorite. He has the financial credentials: Goldman-Sachs, U.S. Treasury, CitiGroup. He raises money for Democrats. And he is credited with the one accomplishment of the Clinton era that all Democrats are proud of: eight years of peacetime economic growth that, by 2000, had produced something pretty close to full employment.
