Dismissed head to get more votes (7)

I believe the answer is:

outpoll

I'm a little stuck... Click here to teach me more about this clue!

'get more votes' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'dismissed head' is the wordplay.
'dismissed' becomes 'out' (dismissed in cricket).
'head' becomes 'poll' (poll is a now rare word for head or scalp).
'out'+'poll'='OUTPOLL'

'to' is the link.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
