Here's what I've been thinking for a while:
Rob has been thinking all along that this cancer thing is no big deal really. I've got tons of money, the best doctors in the country, lots of people beat it, I'm a big strong guy etc. BUT I can milk it for all it's worth, pick up a shit-ton of sympathy votes, get the NightScratcher to play it up and the folks will fall for it. I'll do the sympathy selfie tour, sound real sick, shave the head etc.
Reality is that it's way more serious than he realizes and, with today's prognosis, perhaps he's started to conclude that he's in way deeper than he thought. It's entirely possible that he was diagnosed as early as May and played theses games all summer with a very serious health issue. Of course his entire POS family of power enablers encouraged and went along with everything and likely that hasn't changed.
Hearing him speak today, I was getting a real "I've made a huge mistake" vibe. I could be wrong about some of this but I bet I'm right about at least some of it. On some level, I'd really like to feel some sincere empathy for the big incompetent, racist, wife-beating, narcissistic, homophobic, sociopathic, lying, manipulative prick but he sure doesn't make it easy.
