Why does Obama listen to Geitner rather than Krugman and Stieglitz?

This is a question I've been asking since the beginning of the Obama administration, and has always been a limitation on my general admiration of him. Krugman in his latest makes all too clear that he and those who think like him have been consistently in conformity with reality in their predictions. The Republi-CON opposition has been totally out of touch with reality (except for the reality of getting more money from their rich pay masters,) and the Obama administration has been far too timid in their economic proposals and actions, compared to the challenge the country faces.
