President, unexpected vote loser? (9)
I believe the answer is:
roosevelt
'president' is the definition.
(Theodore Roosevelt or Franklin Delano Roosevelt)
'unexpected vote loser?' is the wordplay.
'unexpected' indicates anagramming the letters.
'vote'+'loser'='voteloser'
'voteloser' is an anagram of 'ROOSEVELT'.
(Other definitions for roosevelt that I've seen before include "former president" , "Leading statesman in war" , "Long-term leader" , "Name of two twentieth century US presidents" , "Teddy" .)
