I admire Stephen Mayne for his energy and enthusiasm (even if I don't always agree with him), but I wonder why he has to try and cover sooo many issues.
Be that as it may, I liked a comment in a recent issue of The Mayne Report, which was, "...revenge is a huge motivator in politics."
Seems to explain a lot of what's going on in Canberra at the present time! Although perhaps the fear that revenge might be taken is an even greater motivator!
EDIT - the following was passed on to me, in light of the above:
embark on a journey of revenge, dig two graves.
