"A Promised Land” memoirist (5)
I believe the answer is:
obama
'a promised land memoirist' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for obama that I've seen before include "Former president" , "Politician" , "one with top job in Washington" , "US president born in Hawaii" , "44th US President" .)
