As far as the public is concerned Plibersek is a fair bit more popular than Albo, thou Albo is more popular than Shorten.
Some thing that may bring on an early election is that LNP MP Craig Kelly id facing a per-selection challenge and he is threatening to sit on the cross bench as an interdependent if he doesn't get per-selection, that is suppose to happen in the next few weeks. Unless LNP win a seat in the by-elections, that would leave them without a majority.
Also talk about Abbott being challenged for pre-selection in his seat, not sure when that will happen but if it happens in the near future and unless LNP win two seats in these by elections Kelly and Abbott would no doubt be a problem and calling an early election would be one way of dealing with them.
