Palin vindicated
In the movie Nicole Wallace is portrayed as a woman who tried so hard to work with a flighty, irrational Sarah Palin until she finally couldn't take it anymore and quit. Palin is portrayed as being paranoid and making unfounded accusations against Wallace for no apparent reason.
In Palin's book Going Rouge, however, a far different story emerges. She talked of Wallace setting her up with Katie Couric interviews at the worst possible times after an already bad interview with her. Couric had an agenda to smear Palin so that Obama could win and would use lowball techniques to irritate Palin until she got a bad response, which would be edited and shown on television.
On May 6, 2015 Wallace admitted on the O'Reilly Factor that she screwed up badly as a handler and that Palin was "rightfully" be angry with her. She said she should never have set up those sabotaging interviews to begin with. In the end Palin was right and this movie was wrong.
