- little political negotiation experience pertinent to the Hill,
- a Congress that either was deceptively and flatly against his agenda or wasn't yet willing to support him in anything verging on the dramatic (i.e., RINOS),

- doubt as to which of those could/would work comfortably with his style of management,
...etc., etc.
