Democrat leading schism in vague movement (5)
I believe the answer is:
drift
'vague movement' is the definition.
'drift' can be an answer for 'movement' (thesaurus). I'm not sure about the 'vague' bit.
'democrat leading schism' is the wordplay.
'leading' says to take the initial letters.
'schism' becomes 'rift' (a schism is a rift between two people or groups).
The first letter of 'democrat' is 'd'.
'd'+'rift'='DRIFT'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for drift that I've seen before include "Gist - snow" , "Be powerless to control movement" , "Snow heaped up by wind" , "state of indecision" , "go with the tide" .)
