I don't know when the taped goodbye from McStain was done, but he sure sounded normal, not like I would have assumed a person with "brain Cancer" would have sounded.
But what if he didn't even have Cancer????? Q asked the question. It's very much a possibilty. Re-read the posts.
Q's post on June 30th leads me to believe there was a trade-off for McStain. POTUS allow him to die with some dignity as long as Cindy McStain votes for Supreme Court Nominee.
