Utter confusion for US president (5)
I believe the answer is:
hayes
'president' is the definition.
(I know that Hayes is a president)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for hayes that I've seen before include "Location in Middlesex" , "Place in Middlesex" , "part of London" , "Former US President" , "Part of Hillingdon" .)
