Doug Holtz-Eakin sourceObama's economic advisors:
Holtz-Eakin is a formerly respected academic and government economist who has been reduced to making distortionary arguments to paper over the massive deficit black hole McCain's tax cuts would create.
Arthur Laffer source
Laffer is the originator of the Laffer curve, the fringe view that claims government revenue increases when tax rates are lowered. There is zero empirical evidence this is true at current tax rates. McCain has repeatedly said that he believes this foolishness, but Holtz-Eakin has said (also repeatedly) that McCain does not.
Phil Gramm source
Gramm is a lobbyist who was vice president of one of the investment houses most heavily implicated in the mortage industry scandal. As a senator he pushed for the banking deregulation that contributed to the current crisis. See more here.
Kevin Hassett source
Hassett has been widely ridiculed for writing the book Dow 36000: The New Strategy for Profiting from the Coming Rise in the Stock Market in 1999, predicting that the Dow would hit 36,000 within five years, if not sooner.
Donald Luskin source
Luskin has been repeatedly named the Stupidest Man Alive by Brad Delong. See here for an example. I can attest based on my own interaction with him a few years back that in addition to being not the sharpest tack in the box, he is also an extremely unpleasant person.
Nancy Pfotenhauer source
Pfotenhauer is a pure distilled product of Koch Industries, an oil company which funds much of the right wing message machine. See here for details.
Carly Fiorina source
Fiorina was spectacularly fired from her previous job as CEO of HP. According to the Times,... Republicans say Ms. Fiorina is using the McCain campaign to rebuild her image after her explosive tenure at Hewlett-Packard. They also say it is hard to see why a woman widely criticized for mismanaging one of Silicon Valley’s legendary companies is advising and representing a candidate who acknowledged last year that he did not understand the economy as well as he should.Regarding Fiorina, Jeffrey Sonnenfeld, the senior associate dean for executive programs at the Yale School of Management, says "What a blind spot this is in the McCain campaign to have elevated her stature and centrality in this way. You couldn’t pick a worse, non-imprisoned C.E.O. to be your standard-bearer.”
Jason Furman (director of economy policy) source bioMy comment on the Laffer curve--Laffer's basic point is obviously correct, that there are points at which raising taxes further would cause revenues to decline and points where lowering taxes further would cause revenues to increase (most obviously at a 100% tax rate), but to the best of my knowledge he never did any empirical or mathematical work to show what the Laffer curve actually looks like and what factors play into it. If you don't know the shape of the curve or where we currently fall on it, you don't know without testing that raising taxes will reduce revenue or lowering taxes will increase revenue. Factcheck.org looks at the actual effects of some U.S. tax cuts in this regard.

I do think that we can speculate that reducing U.S. corporate taxes (currently the highest in the OECD with the exception of Japan) could increase corporate tax revenue, given Ireland's experience with just that happening. Multinational companies will do their best to book their profits in the countries with the lowest corporate tax rates, thus increasing the tax revenue in those countries. Of course, there are other factors, such as regulatory environment, cost of labor, risk of litigation, etc.
