Chose last of ones voted for (8)
I believe the answer is:
selected
'chose' is the definition.
('select' can be a synonym of 'choose')
'last of ones voted for' is the wordplay.
'last of' indicates one should take the final letters.
'voted for' becomes 'elected'.
The final letter of 'ones' is 's'.
's'+'elected'='SELECTED'
(Other definitions for selected that I've seen before include "Chosen or picked" , "Carefully chosen" , "Chose, opted for" , "Chose, picked" .)
