Absolutely not cool. You gotta be kidding me, as Thing 1 and Thing 2 would say. It would be a nightmare.
But the dude's right. The real opposition to the Fords has been spotty at best, IMO, because too many people have been OK with waiting out the clock. If Doug gets elected, those people will be forced to say, "Ok, this isn't ending" and mount serious opposition. I do believe this is true: Doug would be under constant scrutiny, likely facing an opnely hostile council, not to mention his uncanny ability to fuck up everything he touches. He would be as much a marginalized figurehead as Rob ended up, and Council would conduct its business with no regard for his so-called agenda.
John Tory, on the other hand, may actually be able to get some stuff pushed through. And what's on his agenda? The Scarborough subway and SmartTrack, aka "flushing money down the toilet" and "betting Toronto's future on a high-risk loan." One or the other would be bad enough, but both? We've really heard very little else but platitudes. For all these reasons, yeah, Tory is looking like the worse choice in some ways.
