This sounds crude, and I am loath to use the vernacular, but maybe, finally, the time has come for Malcolm Turnbull to “grow a pair”.  

He’s ticking away, inevitably, to losing Newspolls 29 and 30 -- which he used as a major excuse for knifing Tony Abbott. And, even though Abbott was a dead man walking, he and his 2GB barrackers aren’t even waiting for the last two shoes to drop before white-anting the PM. That’s why it is not so far-fetched for the PM to invite a challenge: “Come and get me”. (Remember the time when Prime Minister Abbott almost lost to an empty chair?)
