In the 4 club/assoc I'm in, if only one nomination for a given position, the nominee just gets in.
One has 1200 or so members, so the members actually end up with no vote at all. Not ideal, but what's the alternative. I dunno. To the nominees I say thanks for jumping on board. But be a participant, not just a passenger.
In my 4 groups, these days, nobody wants to nominate, it's a real struggle. The members don't care, they just want someone else/anyone else/everyone else to do everything for them. In my 4 groups, no more than 10% of members turn up to an AGM. They just don't care, as long as it's not them having to do anything. They pay their membership fee, and expect all the things the club does to be provided to them. Not for them, TO them. By someone else/anyone else/everyone else.
And finally, yes, I'm on committees for some, and actively do important sideline stuff for the others.
