From Bill Still:
We also talked to John Doe over a private connection. He talked about what led him to quit the Cruz campaign. He explained that it was over this very complex plan hatched by none other than Amanda Carpenter – a former Cruzer, who had been hired by CNN.
Carpenter rolled out the idea on or about Jan. 15, 2016 – 17 days before the Caucus. The plan was able to manipulate Carson out of delegates that should have voted for him and sent them mostly to Cruz.
