Commit to remove ballot? (6)
I believe the answer is:
devote
'commit' is the definition.
(I know that commit can be written as devote)
'remove ballot?' is the wordplay.
'remove' becomes 'de' (I've seen this in other clues).
'ballot?' becomes 'vote' (balloting is a kind of voting).
'de'+'vote'='DEVOTE'
'to' acts as a link.
(Other definitions for devote that I've seen before include "Resolutely apply" , "Commit" , "Give wholly to" , "Use or dedicate for particular purpose" , "Appropriate to" .)
