Nothing genuine about Democrat's trial (6)
I believe the answer is:
ordeal
'trial' is the definition.
(thesaurus)
'nothing genuine about democrat's' is the wordplay.
'nothing' becomes 'o' (looks like zero - 0).
'genuine' becomes 'real' ('real' is associated in meaning with 'genuine').
'about' indicates putting letters inside.
'democrat' becomes 'd'.
'real' going around 'd' is 'rdeal'.
'o'+'rdeal'='ORDEAL'
(Other definitions for ordeal that I've seen before include "Horrific experience" , "severe test shows" , "Severely trying experience" , "Torture" , "One may be difficult" .)
