I think Abbott is living on borrowed time, but we should see how the staking horse does first. Nightmare scenario for the LNP is for a close leadership to divide the frontbench but Abbott to survive.
Bishop I feel is a more likely choice - Turnbull is utterly despised by half the party.
Recently it seems Aussie parties have the knives out at the ready all the time... Rudd-Gillard-Rudd in the ALP while in government and now potentially something similar with Abbott and the Liberals, Any idea why that is?
Its because under the Australian system it is so ridiculously easy for a party to dump an unpopular leader - all you need is a simple majority vote of caucus on 24 hours notice. If Canada had the same system the Martinites would have ousted Chretien in the late 90s when Martin's followers became a clear majority of the federal Liberal caucus.
