A few thoughts from my armchair:
Ford's win: Pollsters, yet again, missed the ball. Everyone should have seen this coming. As Martin Regg Cohn mentioned in The Star, Ford's win was a backlash against the PC party establishment, solidified under Brown and passed to torch bearers Mulroney and Elliot. Ford has now made relatively safe Liberal pockets in Peel and the Toronto inner burbs (Scarborough, North York and Etobicoke), very competitive.
Wynne's next move: Study everything about Hillary Clinton's campaign, and do the complete opposite. Don't lose sight of your base, don't hold your nose to your opponent's supporters, and forget digging any dirt on your opponent. The Fords, like Trump, are Teflon and will deflect even the harshest allegations or dug up news clips.
Horwath's next move: Study the Bernie and Corbyn playbook: Move further to the left, stick to key populist messaging e.g. "the 99%," and be angry as hell.
