Carter follower (6)
I believe the answer is:
reagan
'carter follower' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for reagan that I've seen before include "40th president of the United States" , "Western star" , "Actor seen in old movies" , "40th US president, Ronald" , "40th US president, d. 2004" .)
