1950s political nickname (3)
I believe the answer is:
ike
'1950s political nickname' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ike that I've seen before include "Thirty fourth US president's nickname" , "Former US President (informally)" , "President Eisenhower's nickname" , "President Eisenhower" , "US general who became president, in short" .)
