Voting breakdown is:
QRU + Reds = 3 votes
ACT + Brumbies = 2 votes
Rugby WA = 1 vote
Rugby SA = 1 vote
That is 7, which is one short of the majority. The article says it is unclear if the Force are aligned with Rugby WA. Not sure where you are getting Tasmania and NT from Sully, they aren't mentioned in the article. All up you'd think its close to curtains for the hammer, I can't imagine every other entity giving him the eight votes he needs.
Personally couldn't really give a rats arse, he will just be replaced by some other wanker, this is worth noting though: "McLennan’s departure would likely see more willingness by states to sign up with Rugby Australia's centralisation plans, according to sources close to the process who spoke anonymously due to the confidential nature of the talks."
