Go with the current Democrat before quarrel (5)
I believe the answer is:
drift
'go with the current' is the definition.
(as in drifting in the water)
'democrat before quarrel' is the wordplay.
'democrat' becomes 'd'.
'before' means one lot of letters go next to another.
'quarrel' becomes 'rift' (I've seen this in other clues).
'd'+'rift'='DRIFT'
(Other definitions for drift that I've seen before include "Float along as on waves" , "Move with the current" , "Movement off course or in general" , "Float along; heap of snow" , "General meaning or flow" .)
