A positive vote from the positive voters? (4)
I believe the answer is:
ayes
'the positive voters?' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'a positive vote' is the wordplay.
'positive vote' becomes 'yes'.
'a'+'yes'='AYES'
'from' is the link.
Can you help me to learn more?
(Other definitions for ayes that I've seen before include "Votes of approval during 5 Down" , "They express assent" , "Those voting for the motion" , "Voting assents" , "Sounds of agreement" .)
