Last time I voted so that a bitter, hostile, elitist, rude & insulting person wouldn't make it into the council as a representative of the community.
vote for the one you think is best of the ones you know about; a vote for him is a vote against the one you despise, after all. And if this level of ignorance is fairly widespread, and is independent of which candidates are known/unknown, it'll all work out.
So this time I didn't even bother.
