Complex vote in the Republic of Argentina? (7)
I believe the answer is:
electra
'complex' is the definition.
(Electra complex is an example)
'vote in the republic of argentina?' is the wordplay.
'vote in' becomes 'elect' (I've seen this before).
'the republic of argentina?' becomes 'ra' (I can't justify this - if you can you should give a lot more credence to this answer).
'elect'+'ra'='ELECTRA'
Can you help me to learn more?
(Other definitions for electra that I've seen before include "Treacle (anag) - daughter of Agamemnon" , "Complex female" , "King's daughter" , "heroine of Greece" , "Greek heroine (with a complex!)" .)
