When Malcolm McKerras first predicted election results he had to allow for senators being stabbed in the Senate  

Now an honorary fellow at Australian Catholic U, Mr Mackerras says the Reps will go to Labor on Saturday with a 1.7 per cent swing, delivering Bill Shorten 79 seats, against 72 for all others. He expects a hung Senate, with three independents holding the balance of power.  Mr Mackerras’ analysis is in Switzer Daily.  It’s another achievement for a bloke present at the foundation of Australian election analysis.
