I don't there's enough of these people. "Ford Nation" isn't as ideologically homogeneous and coherent as both Ford and his detractors seem to think.
Ford received 47% of the vote in 2010. Probably 30% right off the bat were the small-"c" conservative usual suspects. The remaining 17% would have voted for Ford for a myriad of reasons, because he was the most "populist" candidate, seemed the most honest and said what he believed in etc. I recall reading from polls that something like a quarter of Ford's vote either would have either voted for Miller if he was running again or thought he did a good job as mayor. Six months later 3 ridings that voted for Ford municipally voted for the NDP in the orange wave.
It's almost certain that virtually all mainstream conservatives and elite conservatives would bolt to a John Tory or Karen Stintz, while a good number of working class voters would defect as well. With Tory or Stintz capturing "business liberals" and "mainstream conservatives" and Olivia Chow gets the progressive middle classes and a significant share of the working class vote, I don't think Ford's "coalition" would be enough to beat them.
