The only thing that Wynne has going for her is that Tory is not a street-fighter.

She did her political calculus and concluded that stabbing Tory doesn't do anything to hurt her chances of re-election, and in fact likely helps them.

The Mayor of Toronto needs a reputation like that which Richard Daley Sr. had as Mayor of Chicago. The only way any politician outside of Chicago (including the Governor or the President) got the support of Chicago was if they lived up to Daley's demands. Tory will never have that Gravitas because he hasn't built himself a political "machine" that can deliver whatever Tory wants to deliver.

Wynne and Tory deserve each other.
