They're pretty much a spent force in any case. But Singh will probably peel a lot of self-styled prog voters away from the Libs making it more difficult to repeat their majority in 2019/20. And many seniors, concerned about the prospect of losing the pension (a Singh policy) will gravitate to the Cons. So, the biggest losers here are probably the Libs and the biggest winners are the Cons while the NDP will just tread water.
