Chooses second votes (7)
I believe the answer is:
selects
'chooses' is the definition.
('select' can be a synonym of 'choose')
'second votes' is the wordplay.
'second' becomes 's' (common abbreviation).
'votes' becomes 'elects'.
's'+'elects'='SELECTS'
(Other definitions for selects that I've seen before include "Blocks" , "Chooses" , "Picks out" .)
