I to live in Alberta and the drop in oil and natural gas prices has definitely contributed to the vitriol.  But Patrick you are sadly mistaken if you think that is the major reason for the vitriol.
Notley has done virtually nothing for those who have lost their jobs but she has done:
Brought in a carbon tax raising costs (which she did not mention in her campaign)
Allowed her civil servants to get raises
Cost taxpayers more than a billion dollars shutting down coal generation plants before the end of their useful life.
Hurt the agriculture industry.
Given out tax credits amounting to $2 million per full time job.
Refused to cut wasteful civil servant costs.
Saved civil servants jobs even though there were cheaper options

Just a few of the causes of the vitriol directed at Notley.  

btw quoting Redford  is a blatantly ignoring of the fact Redford was well known for berating her staff or that her friend Jensen kept quiet,
