Justis, this late in the electoral cycle there is no turning back for the Coalition; Malcolm Turnbull is da man!
However, IMO the public has warmed to what Turnbull himself has created as his public persona; if he buries his beliefs to appease the likes Murdoch, reactionary MPs in his party and the likes of the IPA, the BCA and the MCA he will lose public support as he cedes that space to other political interests.
For taht reason, as of last night I've detailed these concerns in a personal email to Turnbull - an MP I admire because he has not only read earlier ones from me, he's responded in person to them!
