I'd think Don Martin would have dealt with political actors enough to know when he's being spun. But since his latest post suggests otherwise, let's offer up what looks to be a sorely-needed hint.
When partisan spinners declare that they can't lose, it isn't evidence of cleverness or insight. Instead, it's merely a common instance of self-interested actors using all means available to spread a sense of inevitability to their own self-interest - and it's only newsworthy as evidence of hubris.
Indeed, if the Cons honestly believed that any possible outcome to the NDP's leadership race presented nothing but upside for them, that would be as sure a sign as any that they're vulnerable to some serious losses to come. But I'd give them credit for enough of a link to reality not to fall into such an obvious trap - making it all the more inexcusable that Martin didn't think to question the spin.
