What he's saying is probably true but, as fun as it might be to see the McCains get dragged, Schmidt is still an HP grifter so who care.
This. What's the most fun is that he's making serious allegations about a deceased statesman who's very highly regarded by most of the general public--the greater Atlas community's generally critical view of John McCain is the definition of a "high-information" position that would seem strange to most people who only casually follow politics--yet he's doing so in the format of hours-long personal-beef Twitter tirades against that person's politically irrelevant daughter.
Sounds like peak Atlas to me. 
Is Schmidt secretly an Atlas poster?
