Why they lost the Chicago bid

A fairly reasonable argument put forth in The American Thinker:

Of course Barack and Michelle Obama failed in Copenhagen. Their strategy could not possibly succeed. In their academic arrogance, they thought they could sell a product they clearly do not believe in (the United States) and moreover, they could do so by stressing the benefits to the seller (Chicago) and not the buyer (the IOC). And to top it off, they committed the faux pas of talking too much about the sales force (themselves) and not about the product or the buyer.

Gee, what could possibly go wrong?
