For the good of the once great Liberal party, Scott Morrison has to go
Moreover the coalition needs some time on the opposition benches.
No one in the LNP is now going to overthrow Morrison to own this circus and become the face of electoral defeat. If they had wanted to dump Morrison, they should have done it over six months ago to give the new leader time and some fresh air before the election to try to claw back public support. It's too late now. It's better for the LNP post-election to let Morrison meet karma and then blame and hold him responsible for the expected loss (especially if it's a heavy defeat). It's what the Libs did after McMahon and Fraser lost government. Howard has since 1983 blamed Fraser for losing government to Hawke even though Howard was treasurer at the time when the economy was shot.
ps. The now numerous public attacks on Morrison by his own kind is the beginning of the process. Everyone knew 15 years ago what the lying phony scumbag did to Michael Towke. Just like Gladys' txt messages, the story has only resurfaced now to finish off Morrison for good.
