Council of Economic Advisers: Alan Blinder, who was a member of the CEA and vice chairman of the Federal Reserve under Clinton, would seem ideal to chair this organization. Some potential CEA members would include economists Bill Gale and Peter Orszag, both of the Brookings Institution.
U.S. Trade Representative: Gene Sperling, NEC director under Clinton, would be an excellent choice. A free-trader, he will be needed by Kerry to counter the protectionists who inevitably will be appointed at Labor and Commerce. (I have also heard Gene mentioned as a possible White House chief of staff.) Lael Brainard of Brookings, a top international economist for Clinton, is another possibility.
Federal Reserve: Alan Greenspan will retire at some point in the next four years, giving Kerry the ability to replace him. Former Treasury Secretary Bob Rubin will be at the top of the list of potential chairmen. Should he turn it down, Blinder or Franklin Raines, head of housing giant Fannie Mae, are likely alternatives.
Department of Commerce: Laura Tyson, head of the CEA and NEC under Clinton, would be a good choice here. She is a bit of a protectionist, but not too much, and very knowledgeable on trade and technology issues.
Department of Labor: The unions will demand that Dick Gephardt be given this slot to protect their interests. Should he turn it down, labor economists Lawrence Katz or Harry Holzer are possibilities.
Assistant to the President for Domestic Policy: Sarah Bianchi, Kerry's top policy adviser, is a sure thing unless she desires something better.
Of course, these are all guesses, and being a Republican, I am not exactly plugged in to the Democratic establishment. But all these people are highly competent, have solid records of support for the Democratic Party and, in most cases, served in the Clinton administration in lower level positions. Given that the universe of people qualified for these positions is small, I would be very surprised if most of those I have mentioned didn't end up in some senior capacity in a Kerry administration.
Although I won't be voting for Kerry, I would feel a lot better about his potential for being a good president if I knew that men and women of the caliber I have listed were in fact going to occupy high-level positions. I think naming names would help Kerry win over a few fence-sitters and aid his campaign.
