Indifferent about America returning a Liberal (6)
I believe the answer is:
casual
'indifferent' is the definition.
(thesaurus)
'about america returning a liberal' is the wordplay.
I cannot really understand how this works, but
'about' could be 'ca' (abbreviation for 'circa') and 'ca' is found in the answer.
'america' could be 'a' (common abbreviation - e.g. in organisation names) and 'a' is located in the answer.
'liberal' could be 'l' (abbreviation) and 'l' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for casual that I've seen before include "Irregular" , "Relaxed; informal" , "Informal or cursory" , "Occasional worker" , "Of clothes, not formal" .)
