Deliver vote, for example (3)
I believe the answer is:
say
This clue is a triple definition!
'deliver' is the first definition.
(deliver can mean to say out loud)
'vote' is the second definition.
(as in having a say in a decision)
'for example' is the third definition.
('say' can be used to introduce an example)
(Other definitions for say that I've seen before include "Authority to influence decision" , "Express in words" , "power" , "Articulate" , "Let us suppose" .)
