Like Bill Clinton in 1992, Obama’s campaign boasts a cadre of credentialed achievers. Intellectually, however, the Obamanauts couldn’t be more different. Clinton delighted in surrounding himself with big-think public intellectuals–like economics commentator Robert Reich and political philosopher Bill Galston. You’d be hard-pressed to find a political philosopher in Obama’s inner wonk-dom. His is dominated by a group of first-rate economists, beginning with Goolsbee, one of the profession’s most respected tax experts. A Harvard economist named Jeff Liebman has been influential in helping Obama think through budget and retirement issues; another, David Cutler, helped shape his views on health care. Goolsbee, in particular, is an almost unprecedented figure in Democratic politics: an academic economist with a top campaign position and the candidate’s ear.
