Democrat, after public fury, is exhausted (9)
I believe the answer is:
overtired
'is exhausted' is the definition.
(I've seen this before)
'democrat after public fury' is the wordplay.
'democrat' becomes 'd'.
'after' means one lot of letters go next to another.
'public' becomes 'overt' (both can mean well-known or unconcealed).
'fury' becomes 'ire' (ire is intense rage).
'overt'+'ire'='overtire'
'd' after 'overtire' is 'OVERTIRED'.
(Other definitions for overtired that I've seen before include "Exhausted" , "whacked" , "needing sleep" .)
