Howard was organised, a great leader of the Party/coalition and the Aus nation.
Dutton is easily contrasted with Howard; the problem v. the pinnacle of Liberal success since Menzies.
Dutton is fragmented, disorganised, random and reactionary. Dutton is unlikely to ever become PM because of these very obvious faults.
theres no fear of Dutton as even if he does win an election, he won't last long due to the ambitions of those standing behind him, eg Taylor, who are keen to replace him.
