By effectively telling the Liberal Party that there can be no Coalition while Sussan Ley remains leader, David Littleproud crossed a line. He may not have bought Ley time, but he has, even among her staunchest Liberal detractors, bought her sympathy.
In doing so, he may have done himself a disservice. Because such is the level of anger against Littleproud inside the Liberal Party, there’s a fair chance that he, too, would have to go, as a condition of any reunification.
