Campaign button word (5)
I believe the answer is:
elect
'campaign button word' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for elect that I've seen before include "Put into power through the ballot box" , "Chosen - to vote" , "Bring to office" , "Appoint through ballot" , "Waiting to get into office" .)
