I'm not sure what the problem is - but you certainly can't compare any of these people to the stature of former PM's such as Curtin, Chifley and Menzies. Whitlam I'm not a fan of but at least he had an agenda other than corporate mate-ship after politics.
The other thing that this brings to mind is the serious lack of oratory skills in present day pollies. Their public speaking varies between bad and abysmal.
The two standouts were Menzies and Whitlam; both brilliant speakers who could think on their feet.
Interjector to Menzies: "What are ya gonna do about 'ousing?" Menzies: " Put an "H" in it."
And to Whitlam: "Tell us all you know Gough, it won't take long." Whitlam: "I'll tell you all we both know and it won't take any longer."
