Burn Trump over vote against wine (10)

Ross

I believe the answer is:

chardonnay

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

'wine' is the definition.
(Chardonnay is an example)

'burn trump over vote against' is the wordplay.
'burn' becomes 'char' (charring is a kind of burning).
'trump over' becomes 'don' (I can't explain this - if you can you should give a lot more credence to this answer).
'vote against' becomes 'nay' (I've seen this in another clue).
'char'+'don'+'nay'='CHARDONNAY'

Can you help me to learn more?

(Other definitions for chardonnay that I've seen before include "White wine grape" , "drink" , "Variety of white wine" .)

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