Comfort Liberal supporter (5)
I believe the answer is:
easel
'supporter' is the definition.
'comfort liberal' is the wordplay.
'comfort' becomes 'ease' (easing is a kind of comforting).
'liberal' becomes 'l' (abbreviation).
'ease'+'l'='EASEL'
(Other definitions for easel that I've seen before include "Painting support" , "Artist's canvas suppot" , "Display tripod" , "Van Gogh's stand?" , "Board stanchion" .)
