In the last election I voted for our local Conservative candidate and was actually rather surprised that the Liberals won. To date I have never cast a vote for another party.
However, in the previous election I almost didn't vote when it became apparent that Mr Harper was moving a little too far to the right and was insulting our intelligence by obviously lying to the house about the Duffy affair. When the truth is obvious don't bother to lie, it doesn't do any good. (That was before Trump made lying a daily habit).
At that time I was severely tempted not to vote at all. However, in the end I voted Conservative as it became evident that the election was going to go Liberal anyway and I didn't want them to get too confident in their position.
That transparent enough?
