Which party leader is really ‘authentic’?

Sirs  
I was surprised to read David Chandler’s opinion that to describe someone as ‘authentic’ is not a compliment. So I looked up the meaning of ‘authentic’ in two dictionaries.
 
Collins English Dictionary: ‘accurate in representation of the facts; trustworthy; reliable’ .

Webster’s New World College Dictionary, 4th Edition:  ‘can be believed or accepted; trustworthy; reliable’.  
OPPOSITES:  ‘spurious, counterfeit, sham’.
 
Readers will make up their own minds which of the two leaders in this election is most authentic and best suited to be Prime Minister.
