“Unfortunately for me this trial looks like that. It's going to destroy the current incarnation of the Liberal party from what I can see.”
This is an overly catastrophic statement.
This trial will not ‘destroy’ the current incarnation of the Liberal Party. It will likely force a removal of the leadership team in Victoria.
In Victoria only.
Australian political parties are quite regularly spilling leaders at state and national level. It doesn’t ‘destroy’ them. Because the factions have always been in the parties and they cycle through.
Having a change in leadership now will be wise to allow the new leader to settle in.
Considering one of the contenders this time around was beaten by one vote last time, it seems overly dramatic to suppose that he could not have the same degree of support at least this time around. I doubt any challenger would mount this challenge if they did not have confidence that one of them will beat Pesutto.
