Makes immortal and gives reality to losing vote (11)

I believe the answer is:

eternalises

'makes immortal' is the definition.

'gives reality to losing vote' is the wordplay.
'gives reality to' becomes 'externalises'.
'losing' is a deletion indicator.
'vote' becomes 'x' (how votes are marked).
'externalises' with 'x' taken out is 'ETERNALISES'.

'and' is the link.

I've seen this clue in The Guardian.
