When she sent Podesta out, I honestly think she believed that the "Deep State" had a Plan B ready to go, some extra ballot boxes appearing at the last minute in Michigan, Wisconsin and Pennsylvania. Remember Podesta said something that night about "All the votes still to be counted". It was only after she was informed there was no Plan B (because nobody in the deep state had bothered to create one assuming she would win in a landslide) that she finally conceded.
Wile E was in charge of the plan B.
