Presuming the lack of an underground move by Bishop, the spill will be unsuccessful. Over 40 MPs have already come out publicly against it, with less than 15 publicly supporting it. Obviously many of the 40 or so quiet ones will support it, but given some of the names on that list, it definitely won't be all.
The Turnbull camp is saying they're hopeful it'll be even, but most others predict they'll get no more than 40 MPs voting for the spill. So I only see the motion as passing if Bishop, and her supporters within the party room, switch positions and vote for it.
One of Turnbull's biggest issues, a bit like Kevin Rudd, is that he simply doesn't have allies in the party room. In Rudd's case, it was a matter of a lack of personal popularity amongst MPs; while for Turnbull it's both that (Coalition MPd form groupings, Turnbull is way on his own; as well as him pissing off most of his colleagues) alongside very few ideological buddies. He does have a few supporters, lumped in with some panicking marginal MPs, but not the sturdiest support base.
Nek minnit I'm completely wrong tomorrow morning.
