Hager has responded to Brash’s rebuttal.
In it he uses the same tactics he uses in the book – read everything he can into what is said and twist it to his own ends.
I think a quote from his conclusion should be sufficient:
The most notable feature of Don Brash’s rebuttal, of course, is that he does not mention or bother to respond to all the hundreds of pages of revelations about his party where he was unable to find fault.
Ah Ha! Brash is not Superman, and is therefore not qualified to lead the National Party.
