Ultimately they receive a positive vote (3)
I believe the answer is:
yea
'positive vote' is the definition.
(I've seen this in another clue)
'ultimately they receive a' is the wordplay.
'ultimately' says to take the final letters.
The last letters of 'they receive' are 'ye'.
'ye'+'a'='YEA'
(Other definitions for yea that I've seen before include "Affirmative in the British Parliament" , "Aye; aye (anag.)" , "I'm pro" , "Archaic affirmative answer" , "Affirmative, colloquially" .)
