Canadians shouldn't be unduly concerned if Ms. Craft is closely aligned with and has the ear of the President (this is to our advantage) or that her family has coal interests etc.  The real need is that she understands her role as ambassador and has the smarts and tact to act as an intelligent conduit for ongoing constructive communication between the 2 Governments.

Given that US ambassadors to Canada are traditionally patronage appointments and not career diplomats, she appears to be an OK choice.
