I certainly don't doubt that Soknacki could potentially be a decent mayor, the problem lies in the fact that he's not a household name like Ford, who can use his multiple bully pulpits to ruin Soknacki's reputation even before the campaigns starts.
Thinking about the whole subway-LRT debacle a bit, I realize that I'm not really opposed to Ford's plans. What I'm opposed to is his hypocrisy in demanding more subways whilst reject ways of paying for them, essentially ensuring that nothing gets done. It reeks of a mayor who's not interested in actually having transit built, someone who talks the talk but who refuses to walk the walk.
This is essentially the base of the issue and why it hasn't been settled. Ford wants subways, but he refuses to pay for them. People want subways, but are convinced by Ford that they don't need to pay for them. The argument has essentially turned from LRTs vs subways, to LRTs vs nothing. If Ford had scuttled Transit City, but had also endorsed a new, comprehensive plan of how to pay for them, this would be done by as smoothly as butter on a baby's back.
