By what yardstick is Kenny a great leader?

By any yardstick you would have to say that he is an outstanding citizen, but, for the life of me, I am struggling to identify that yardstick by which he places Enda Kenny on a possible list of great taoisaigh (Irish Examiner, May 10).
Enda Kenny has presided over a government far removed from that which was elected to serve the people and the common good. Their dirty tricks toolbox has included lack of transparency and accountability and delaying tactics when faced with resolving scandal after scandal, “trial by innuendo” when trying to gain political advantage over opponents, appointments of their ilk to high places shoring up their ability to hold on to power when the need arises. Demonstrations of incompetence abound during his tenure, not to mention the erosion of civil liberties. The list goes on and on.
