There's a good chance he'll be mayor again though if his health holds up. The guy's still young! Especially with the Sun's frontpage treatment. I bet he gets a radio show or a regular segment again too.
A good chance? Nah. He has "a" chance but a lot stars have to line up. Once the crack scandal took root, support for the Fords stalled a pretty solid 30-35%. The remainder of the support coalesced around different people at different times, but Rob and Doug never really moved. If Rob returns to heatlh — something he seems to having trouble with, turmors or not — he'll need a big field of candidates to the split a vote in his favour. That's less likely in a race with an incumbent. I'm not saying it couldn't — Tory could flame out as he has in the past — but I don't see Rob have a "good" chance in 2018. I guess we'll see.
