I confess I strongly dislike Politics in general and most politicians in particular (they are right up there with used car salespersons, lawyers, advertisers and Estate agents, and Journalists as Liars and cheats), but I ALWAYS vote. I have an infallible(for me) way of deciding how to vote in elections, which I commend to you.
I found many years ago that frequently there is NO ONE I want to vote FOR but there is ALWAYS someone(or party) I want to vote AGAINST!!!! and that Is what I do I vote for the party or individual I dislike least. This works for me, draw up a table and put on it the partys and what bad things each party has done in the last parliament, (local authority session, period of office,) and vote for the ones with the shortest list, Miccas Motto " when in doubt Vote Against"
