Get rid of Democrat before long (5)
I believe the answer is:
ditch
'get rid' is the definition.
(I've seen this before)
'democrat before long' is the wordplay.
'democrat' becomes 'd'.
'before' says to put letters next to each other.
'long' becomes 'itch' (to long or itch for something is to desire it).
'd'+'itch'='DITCH'
'of' acts as a link.
(Other definitions for ditch that I've seen before include "long depression" , "Get rid of; dug channel" , "Dump; channel" , "Type of trench" , "Throw away (sl.)" .)
