Maine politician n the man's in a city elsewhere (7)
I believe the answer is:
memphis
'a city elsewhere' is the definition.
I can't judge whether this definition defines the answer.
'maine politician n the man's in' is the wordplay.
'maine' becomes 'me'.
'politician n' becomes 'phi' (I can't justify this - if you can you should give a lot more credence to this answer).
'the man's' becomes 'ms'.
'in' is an insertion indicator.
'phi' put into 'ms' is 'mphis'.
'me'+'mphis'='MEMPHIS'
Can you help me to learn more?
(Other definitions for memphis that I've seen before include "City of Tennessee/Egypt" , "Name of city at different times overlooking the Nile and Mississippi?" , "US city where Gracelands is located" , "Ancient Egyptian city" , "Largest city in Tennessee" .)
