It's Because They Don't Like You That Way

It appears that the Obama transition team is not interested in attempts by Bush and His Evil Minions^™ to work together on the bailout, and this is of concern to members of the Bush economic team:

But tension is growing: Treasury officials believe Obama aides are being short-sighted in their refusal to offer more policy and lobbying assistance, while the transition team sees an administration looking to be rescued from its own miscues.

Obama and the people around him most likely think that George W. Bush and Hank Paulson and their people are incompetent and corrupt, and they believe to the degree that these folks do not take action, it is a positive development.

Any attempt to work with Paulson or Bush will imply buy ins of their policy, and that it like buying into the ice concession on the RMS Titanic.
