I'd certainly agree that if they can't communicate about their own
position, the chances of them being an effective council member are slim.
But, there is no mechanism to strike them from the list; nor should
there be. Who gets to decide if someone's clarified their position well
enough? What if all a candidate does is espouse FUD which has been
regularly knocked back?

The point of an election is to have the electorate decide who to represent
them. If a candidate doesn't realise that the everyone eligible to vote
will be emailed a ballot (including a link to the above wiki page) and
relies on their name on a subset of the community (and the wild hallways of
TMO aren't the extent of the community), they should be rejected by
the electorate with a simple cry of "who?"
