Assume that you are (not self-) nominated in moderator elections, the bulk of the votes are cast already, and it looks as if you will be among the winners. But you know that some of the other less upvoted candidates are (much) more knowledgeable about the topic of the site ...
Is such a situation a reason to reject the nomination as a moderator, in order to make the most competent about the site topic candidates win?
Assume that in the community in question it is rather important, that the moderators are knowledgeable (in the real-world respected experts at best) about the site topic too.
What additionally complicates the situation a bit (yes, due to suboptimal organization I know ...) is the fact that it is not yet known for sure, which candidates will finally accept their election in the first place.
