Tasks on election night for noble fellows (6)
I believe the answer is:
counts
This clue is a double definition.
'tasks on election night' is the first definition.
(counting ballots)
'noble fellows' is the second definition.
(count is a type of aristocrat or nobleman)
'for' is the link.
(Other definitions for counts that I've seen before include "Numbers" , "Determines the number of" , "Enumerates like minor aristocracy" .)
