Madison or Monroe (5)
I believe the answer is:
james
'madison or monroe' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for james that I've seen before include "Capt. - Cook, explorer" , "Henry --, US novelist" , "The first king of England and Scotland" , "Jesse ___, US outlaw (1847-82)" , "Boy's name" .)
