Spoke total sense at last to Democrat (7)
I believe the answer is:
uttered
'spoke' is the definition.
('utter' can be a synonym of 'speak')
'total sense at last to democrat' is the wordplay.
'total' becomes 'utter' (I've seen this before).
'sense at last' becomes 'e' (I can't justify this - if you can you should believe this answer much more).
'to democrat' becomes 'd'.
'utter'+'e'+'d'='UTTERED'
(Other definitions for uttered that I've seen before include "Pronounced" , "Spoken" , "In law, put forged money into circulation" , "Spoke and put into circulation" , "Said (something)" .)
