With his Quebec advantage somewhat neutralized and Broadbent’s sought-after endorsement spoken for by a rival who happens to be a better-connected insider, Mulcair has to all intents and purposes gone from unofficial pack leader to underdog in the early leadership sweepstakes.
That is no accident.
Among the prospective candidates, none worked more closely with Layton than Topp. He was at the late leader’s side until the very end.
On that basis, one can reasonably assume that if Layton had seen Mulcair — who would bring proven electoral success, cabinet experience and a Quebec household name to the fore of a leadership bid — as his natural successor, Topp would still be backstage running the party rather than auditioning for the lead opposition role in Parliament.
