Sounds like it's pretty serious. To be honest, I was hoping to see him destroyed at the polls and then shortly after hauled off in handcuffs, fighting and being his belligerent self all the way along. What if cops really were investigating Rob for Smith's murder--do they still move forward trying to prove that if Rob's health issues are the worst case scenario?
He's used the illness card before, this is no different. Danger or not, the Fords will use anything to push the Ford Family Compact, including preying on people just like all those cancer frauds on the web asking people for money.
Robbie doesn't quit, well, not unless you count college and a few other things, so using health, that's a free pass for him. You can't blame him, with Braven 2, all the COI, election policy deviations, etc. Robbie can't actually win, even if he got reelected, morally he destroyed his career as a MINO.
If the TPS stall or quit for Robbie's "health issues" then they do need to be replaced. If he did the crimes then convict him, if they don't then it is an insult to Torontonians.
That said, no one should deal with the health issues he has, and they should be addressed. If it's cancer, that has to be dealt with, all the other problems are on him. If he comes out on the shitty end of the stick due to his and his deeds, then to bad, he has to lie in that bed, even if it costs him his life; martyrism is a tough shtick.
