The conventional wisdom is that Obama will fill the very critical Secretary of the Treasury post with either Tim Geithner (NY Fed President), Paul Volcker (former Fed Chairman), Larry Summers (former Treasury Secretary), or Robert Rubin (former Treasury Secretary).  Some also mention Warren Buffet (unlikely) and Jon Corzine (NJ Governor and former Goldman Sachs chief) as possibilities.

Clearly and impressive list, but where's the change we can count on?  If Obama is of a mind to be bold and also to deliver on his bi-partisan and diversity pledges, he might want to consider Sheila Bair, the Republican appointed Chairwoman of the FDIC.  Bair has been at the forefront of the financial crisis and has been innovative in her approaches to stemming the meltdown tide, particularly in the housing market.  She's actually shown much more interventionist tendencies than many limited government Republicans would prefer.  That makes her near perfect for Democrat purposes.  She can carry the flag for an enormous housing rescue plan, for far-reaching regulation of the financial markets, as well as for plans to pump huge amounts of money into the auto and other troubled industries...and she can do it all as a Republican.  That won't eliminate the cries from the right, but it would definitely blunt a good bit of their criticism.
