Why am I replying to this hopefully any debate is engaging and safe lol It is not exactly fair to condemn a political leader or to disparage their leadership ability due to their marital relations. Marital relationships are vastly different from national and global politics.
Regarding your comments about shifting loyalties, literally every single politician ever has had a 'shift in loyalty', especially in Australia where parites have replaced the Prime Minister at least a couple of times during the same term (eg. Gillard and Rudd and Tony Abbott and Malcolm Turnbull and Turnbull and Scott Morrison). To say that Shorten is going to ruin Australia from this statement is also unreasonable; you must judge Morrison and various other party members (eg. Cory Bernardi, Abbott and I believe there may have been various One Nation 'defectors'?) by the same criteria.
Also, criminals are only those who are convicted of crimes and Shorten has not, to my knowledge, been convicted of any crime. I am sure that if he was guilty, that bribery, etc. on a national scale would be sorted and that if these allegations had any substance, that there would be more widespread media backlash than what there currently seems to be, unless this has already spilled over.
Your sources are also those that are highly biased against Labor eg. the 2 Andrew Bolt articles that you have linked. Also note that Andrew Bolt rarely provides mostly factual and unbiased material- he is, after all, an opinion writer.
It is also unreasonable to say that Labor does not deserve votes (if this is what you are saying) because of the supposed incompetence of their leader since governments' effectiveness is mostly determined by the skills and competence of the entire 'team' (what is the technical term?)
Just some things to think about.
