He says he wants bipartisanship. Why would he permit his congressional allies to kill any hope of bipartisanship by their egregious conduct?

I can think of four possible explanations for this almost unprecedented presidential detachment from the decision making of policies the president publicly declared to be vital to the country and his presidency:

1) He is a very, very big-picture man, and he delegates decisions even on the central points of vital issues.

2) For tactical reasons, he decided these matters were not worth using up political chits.

3) He is either hesitant or unskilled at management, and he let matters drift until it seemed too late to intervene personally.

4) Or his personality type leaves him surprisingly uninterested in things that aren't personally about him.

Whatever the reason, this level of presidential detachment from high policy decision making is dangerous in a White House that has so many czars and other senior players (the West Wing staff is reputed to be more than 130 -- about double the usual number) combined with emissaries and strong-willed Cabinet secretaries. It may well lead to what has been called (regarding another country's government) "the immanent structurelessness to the running of the state."
