You can think about it in depth if you choose to exercise your right not to vote, plus you haven't jumped through the ludicrous loop of turning up not to that dome others want to compel you to do. You do, of course, have every right to complain if the individual unfit candidate chosen by others proves as awful as you suspected they might, and you hold no blame for electing them; unlike some others.
I shall be helping my choice to come third today. This is no marginal constituency.
