Misguided voter that's obvious (5)
I believe the answer is:
overt
'obvious' is the definition.
(similar in meaning)
'misguided voter' is the wordplay.
'misguided' indicates anagramming the letters (I've seen this in other clues).
'voter' with letters rearranged gives 'OVERT'.
'that's' acts as a link.
(Other definitions for overt that I've seen before include "Open to view" , "Plain to see - manifest" , "Trove (anag.)" , "Conspicuous" , "Open and candid" .)
