Follower; supporter (8)
I believe the answer is:
adherent
I believe this is a double definition.
'follower' is the first definition.
(I know that adherent is a type of follower)
'supporter' is the second definition.
(I've seen this before)
(Other definitions for adherent that I've seen before include "lover" , "One supports" , "supporter of party" , "sticker" , "Weep" .)
